tmpfile



PURPOSE

Creates a temporary file.

LIBRARY

Standard I/O Library (libc.a)

SYNTAX

#include <stdio.h>

FILE *tmpfile ( )

DESCRIPTION

The tmpfile subroutine creates a temporary file and returns its FILE pointer.
The file is opened for update.

The temporary file is automatically deleted when the process using it
terminates.

If the file cannot be opened, tmpfile writes an error message to the standard
error output and returns a NULL pointer.

ERROR CONDITIONS

The tmpfile subroutine may fail if the following are true:

EACCES    Search permission is denied on a component of the path prefix of the
          file to be created, or write permission is denied for the parent
          directory of the file to be created.

EINTR     A signal was caught during the tmpfile subroutine.

ENOMEM    Insufficient storage space is available.

ENOTDIR   A component of the path prefix of the file to be created is not a
          directory.

EROFS     The file to be created would reside on a read-only file system.
