-.TH TRUNCATE 2 1998-12-21 "" "Linux Programmer's Manual"
-.SH NAME
-truncate, ftruncate \- truncate a file to a specified length
-.SH SYNOPSIS
-.B #include <unistd.h>
-.sp
-.BI "int truncate(const char *" path ", off_t " length );
-.br
-.BI "int ftruncate(int " fd ", off_t " length );
-.SH DESCRIPTION
-The
-.B truncate
-and
-.B ftruncate
-functions cause the regular file named by
-.I path
-or referenced by
-.I fd
-to be truncated to a size of precisely
-.I length
-bytes.
-.LP
-If the file previously was larger than this size, the extra data is lost.
-If the file previously was shorter, it is extended, and
-the extended part reads as zero bytes.
-.LP
-The file pointer is not changed.
-.LP
-With
-.BR ftruncate ,
-the file must be open for writing; with
-.BR truncate ,
-the file must be writable.
-.SH "RETURN VALUE"
-On success, zero is returned. On error, \-1 is returned, and
-.I errno
-is set appropriately.
-.SH ERRORS
-For
-.BR truncate :
-.TP
-.B EACCES
-Search permission is denied for a component of the path prefix,
-or the named file is not writable by the user.
-.TP
-.B EFAULT
-.I Path
-points outside the process's allocated address space.
-.TP
-.B EFBIG
-The argument
-.I length
-is larger than the maximum file size. (XSI)
-.TP
-.B EINTR
-A signal was caught during execution.
-.TP
-.B EINVAL
-The argument
-.I length
-is negative or larger than the maximum file size.
-.TP
-.B EIO
-An I/O error occurred updating the inode.
-.TP
-.B EISDIR
-The named file is a directory.
-.TP
-.B ELOOP
-Too many symbolic links were encountered in translating the pathname.
-.TP
-.B ENAMETOOLONG
-A component of a pathname exceeded 255 characters,
-or an entire path name exceeded 1023 characters.
-.TP
-.B ENOENT
-The named file does not exist.
-.TP
-.B ENOTDIR
-A component of the path prefix is not a directory.
-.TP
-.B EROFS
-The named file resides on a read-only file system.
-.TP
-.B ETXTBSY
-The file is a pure procedure (shared text) file that is being executed.
-.PP
-For
-.B ftruncate
-the same errors apply, but instead of things that can be wrong with
-.IR path ,
-we now have things that can be wrong with
-.IR fd :
-.TP
-.B EBADF
-The
-.I fd
-is not a valid descriptor.
-.TP
-.BR EBADF " or " EINVAL
-The
-.I fd
-is not open for writing.
-.TP
-.B EINVAL
-The
-.I fd
-does not reference a regular file.
-.SH "CONFORMING TO"
-4.4BSD, SVr4 (these function calls first appeared in BSD 4.2).
-POSIX 1003.1-1996 has
-.BR ftruncate .
-POSIX 1003.1-2001 also has
-.IR truncate ,
-as an XSI extension.
-.LP
-SVr4 documents additional
-.B truncate
-error conditions EMFILE, EMULTIHP, ENFILE, ENOLINK. SVr4 documents for
-.B ftruncate
-an additional EAGAIN error condition.
-.SH NOTES
-The above description is for XSI-compliant systems.
-For non-XSI-compliant systems, the POSIX standard allows
-two behaviours for
-.B ftruncate
-when
-.I length
-exceeds the file length
-(note that
-.B truncate
-is not specified at all in such an environment):
-either returning an error, or extending the file.
-(Most Unices follow the XSI requirement.)
