-+=head1 DESCRIPTION
-+
-+This library implements a generic hook interface for Apache which can be used
-+to loosely couple code through arbitrary hooks. There are two use cases for
-+this mechanism:
-+
-+=over 3
-+
-+=item B<1. Extension and Overrides>
-+
-+Inside a specific code section you want to perform a specific function call
-+for extension reasons. But you want to allow one or more modules to implement
-+this function by registering hooks. Those hooks are registered on a stack and
-+can be even configured to have a I<decline> return value. As long as there are
-+functions which return the decline value the next function on the stack is
-+tried. When the first function doesn't return the decline value the hook call
-+stops.
-+
-+The original intent of this use case is to provide a flexible extension
-+mechanism where modules can override functionality.
-+
-+=item B<2. Intercommunication>
-+
-+Inside a specific code you have a function you want to export. But you first
-+want to allow other code to override this function. And second you want to
-+export this function without real object file symbol references. Instead you
-+want to register the function and let the users call this function by name.
-+
-+The original intent of this use case is to allow inter-module communication
-+without direct symbol references, which are a big I<no-no> for the I<Dynamic
-+Shared Object> (DSO) situation.
-+
-+=back
-+
-+And the following design goals existed:
-+
-+=over 3
-+
-+=item B<1. Minimum code changes>
-+
-+The hook calls should look very similar to the corresponding direct function
-+call to allow one to easily translate it. And the total amount of changes for
-+the hook registration, hook configuration and hook usage should be as small as
-+possible to minimize the total code changes. Additionally a shorthand API
-+function (ap_hook_use) should be provided which lets one trivially add a hook
-+by just changing the code at a single location.
-+
-+=item B<2. The hook call has to be maximum flexible>
-+
-+In order to avoid nasty hacks, maximum flexiblity for the hook calls is
-+needed, i.e. any function signature (the set of types for the return value and
-+the arguments) should be supported. And it should be possible to
-+register always a context (ctx) variable with a function which is passed to
-+the corresponding function when the hook call is performed.
-+
-+=back
-+
-+The implementation of this library directly followed these two design goals.
-+
-+=head1 USAGE
-+
-+Using this hook API is a four-step process:
-+
-+=over 3
-+
-+=item B<1. Initialization>
-+
-+Initialize or destroy the hook mechanism inside your application program:
-+
-+ ap_hook_init();
-+ :
-+ ap_hook_kill();
-+
-+=item B<2. Configuration>
-+
-+Configure a particular hook by specifing its name, signature and return type
-+semantic:
-+
-+ ap_hook_configure("lookup", AP_HOOK_SIG2(ptr,ptr,ctx), AP_HOOK_DECLINE(NULL));
-+ ap_hook_configure("setup", AP_HOOK_SIG2(int,ptr,char), AP_HOOK_DECLTMP(FALSE));
-+ ap_hook_configure("read", AP_HOOK_SIG2(void,ptr), AP_HOOK_TOPMOST);
-+ ap_hook_configure("logit", AP_HOOK_SIG2(void,ptr), AP_HOOK_ALL);
-+
-+This configures four hooks:
-+
-+A hook named C<lookup> with the signature C<void *lookup(void *, void *)>
-+(where the second argument is C<NULL> or the private context pointer of the
-+hook function which can be optionally provided at the registration step
-+later) and a return code semantic which says: Proceed as long as the
-+registered lookup functions return C<NULL> or no more registered functions
-+exists. A call for this hook has to provide 2 argument only (a pointer to the
-+return variable and the first argument), because the context is
-+implicitly provided by the hook mechanism. Sample idea: I<The first function
-+who was successful in looking up a variable provides the value>.
-+
-+A hook named C<setup> with the signature C<int setup(void *, char)" and a
-+return code semantic equal to the one of the C<lookup> hook. But the decline
-+return value is implemented by a temporay variable of the hook mechanism and
-+only used for the decline decision. So a call to this hook has to provide 2
-+arguments only (the first and second argument, but no address to a return
-+value). Sample idea: I<Any function can handle the setup and when one
-+function handled it stops the processing by indicating this with the return
-+value>.
-+
-+A hook named C<read> with the signature C<void read(void *)> and a return code
-+semantic which says: Only the top most function on the registered function
-+stack is tried (and independet of a possible return value in non-void
-+context). A call to this hook has to provide exactly 1 argument (the
-+single argument to the hook function). Sample idea: I<We want to
-+use a read function and allow others to override it, but independent how much
-+registered functions exists, only top most (= last registered) function
-+overrides and is used>.
-+
-+A hook named C<logit> with the signature C<void logit(void *)> and a return
-+code semantic which says: All registered functions on the hook functioin stack
-+are tried. Sample idea: I<We pass a FILE pointer to the logging functions and
-+any function can log whatever it wants>.
-+
-+=item B<3. Registration>
-+
-+Register the actual functions which should be used by the hook:
-+
-+ ap_hook_register("lookup", mylookup, mycontext);
-+ ap_hook_register("setup", mysetup);
-+ ap_hook_register("read", myread);
-+ ap_hook_register("logit", mylogit);
-+
-+This registers the function C<mylookup()> under the C<lookup> hook with the
-+private context given by the variable C<mycontext>. And it registers the
-+function C<mysetup()> under the C<setup> hook without any context. Same for
-+C<myread> and C<mylogit>.
-+
-+=item B<4. Usage>
-+
-+Finally use the hooks, i.e. instead of using direct function calls like
-+
-+ rc = mylookup(a1, a2);
-+ rc = mysetup(a1, a2);
-+ myread(a1);
-+ mylogit(a1);
-+
-+you now use:
-+
-+ ap_hook_call("lookup", &rc, a1, a2);
-+ ap_hook_call("setup", &rc, a1, a2);
-+ ap_hook_call("read", a1);
-+ ap_hook_call("logit", a1);
-+
-+which are internally translated to:
-+
-+ rc = mylookup(a1, a2, mycontext);
-+ rc = mysetup(a1, a2);
-+ myread(a1);
-+ mylogit(a1);
-+
-+Notice two things here: First the context (C<mycontext>) for the C<mylookup()>
-+function is automatically added by the hook mechanism. And it is a different
-+(and not fixed) context for each registered function, of course. Second,
-+return values always have to be pushed into variables and a pointer to them
-+has to be given as the second argument to C<ap_hook_call> (except for
-+functions which have a void return type, of course).
-+
-+BTW, the return value of C<ap_hook_call()> is always C<TRUE> or C<FALSE>.
-+C<TRUE> when at least one function call was successful (always the case for
-+C<AP_HOOK_TOPMOST> and C<AP_HOOK_ALL>). C<FALSE> when all functions
-+returned the decline value or no functions are registered at all.
-+
-+=back
-+
-+=head1 RESTRICTIONS
-+
-+To make the hook implementation efficient and to not bloat up the code too
-+much a few restrictions have to make:
-+
-+=over 3
-+
-+=item 1.
-+
-+Only function calls with up to 4 arguments are implemented. When more are
-+needed you can either extend the hook implementation by using more bits for
-+the signature configuration or you can do a workaround when the function is
-+your own one: Put the remaining (N-4-1) arguments into a structure and pass
-+only a pointer (one argument) as the forth argument.
-+
-+=item 2.
-+
-+Only the following ANSI C variable types are supported:
-+
-+ - For the return value:
-+ void (= none), char, int, float, double, ptr (= void *)
-+ - For the arguments:
-+ ctx (= context), char, int, float, double, ptr (= void *)
-+
-+This means in theory that 6^5 (=7776) signature combinations are possible. But
-+because we don't need all of them inside Apache and it would bloat up the code
-+too dramatically we implement only a subset of those combinations. The
-+implemented signatures can be specified inside C<ap_hook.c> and the
-+corresponding code can be automatically generated by running ``C<perl
-+ap_hook.c>'' (yeah, no joke ;-). So when you need a hook with a different
-+still not implemented signature you either have to again use a workaround as
-+above (i.e. use a structure) or just add the signature to the C<ap_hook.c>
-+file.
-+
-+=head1 EXAMPLE
-+
-+We want to call `C<ssize_t read(int, void *, size_t)>' through hooks in order
-+to allow modules to override this call. So, somewhere we have a replacement
-+function for C<read()> defined (same signature, of course):
-+
-+ ssize_t my_read(int, void *, size_t);
-+
-+We now configure a C<read> hook. Here the C<AP_HOOK_SIGx()> macro defines the
-+signature of the C<read()>-like callback functions and has to match the
-+prototype of C<read()>. But we have to replace typedefs with the physical
-+underlaying ANSI C types. And C<AP_HOOK_DECLINE()> sets the return value of
-+the read()-like functions which forces the next hook to be called (here -1).
-+And we register the original C<read()> function as the default hook.
-+
-+ ap_hook_configure("read",
-+ AP_HOOK_SIG4(int,int,ptr,int),
-+ AP_HOOK_DECLINE(-1));
-+ ap_hook_register("read", read);
-+
-+Now a module wants to override the C<read()> call and registers the
-+C<my_read()> function:
-+
-+ ap_hook_register("read", my_read);
-+
-+The function logically gets pushed onto a stack, so the execution order is the
-+reverse registering order, i.e. I<last registered - first called>. Now we can
-+replace the standard C<read()> call
-+
-+ bytes = read(fd, buf, bufsize);
-+ if (bytes == -1)
-+ ...error...
-+
-+with the hook based call:
-+
-+ rc = ap_hook_call("read", &bytes, fd, buf, bufsize);
-+ if (rc == FALSE)
-+ ...error...
-+
-+Now internally the following is done: The call `C<bytes = my_read(fd, buf,
-+bufsize)>' is done. When it returns not -1 (the decline value) nothing
-+more is done. But when C<my_read()> returns -1 the next function is tried:
-+`C<bytes = read(fd, buf, bufsize)>'. When this one also returns -1 you get
-+`rc == FALSE'. When it finally returns not -1 you get `rc == TRUE'.

-+<P>
-+The <CODE>Define</CODE> directive defines a variable which later can be
-+expanded with the unsafe but short construct
-+``<CODE>$</CODE><EM>variable</EM>'' or the safe but longer construct
-+``<CODE>${</CODE><EM>variable</EM><CODE>}</CODE>'' on any configuration line.
-+Do not intermix this with the third-party module <CODE>mod_macro</CODE>. The
-+<CODE>mod_define</CODE> module doesn't provide a general macro mechanism,
-+although one can consider variable substitutions as a special form of macros.
-+Because the value of to which ``<CODE>$</CODE><EM>variable</EM>'' expands has
-+to fit into one line. When you need macros which can span more lines, you've
-+to use <CODE>mod_macro</CODE>. OTOH <CODE>mod_macro</CODE> cannot be used to
-+expand a variable/macro on an arbitrary directive line. So, the typical use
-+case of <CODE>mod_define</CODE> is to make strings <EM>variable</EM> (and this
-+way easily changeable at one location) and not to <EM>bundle</EM> things
-+together (as it's the typical use case for macros).
-+
-+<P>
-+The syntax of the expansion construct (
-+``<CODE>${</CODE><EM>variable</EM><CODE>}</CODE>'') follows the Perl and Shell
-+syntax, but can be changed via the <CODE>Define</CODE> directive, too. Four
-+internal variables can be used for this. The default is:
-+
-+<BLOCKQUOTE>
-+<PRE>
-+Define mod_define::escape "\\"
-+Define mod_define::dollar "$"
-+Define mod_define::open "{"
-+Define mod_define::close "}"
-+</PRE>
-+</BLOCKQUOTE>
-+
-+<P>
-+When you need to escape some of the expansion constructs you place the
-+mod_define::escape character in front of it. The default is the backslash as
-+in Perl or the Shell.

-+**
-+** 2. When the MM library cannot be built on the current platform
