#include <stdio.h> FILE *tmpfile(void);
tmpfile creates a temporary file.
You can open the file for both reading
and writing. When you close the file, it is deleted. Note that the
meanings of the words create and temporary are
system dependent.
For programs compiled with the posix option, the temporary file created
by tmpfile is an HFS file in the directory /tmp. For
non-posix-compiled programs, the file is an MVS or CMS disk file
suitable for "rel" access. For MVS non-posix-compiled programs,
a file created by tmpfile is a true temporary file, and is deleted
at the end of the job step or TSO session, even if the program terminates
abnormally. For posix-compiled programs or programs on CMS, a file
created by tmpfile is not deleted if the calling program is
terminated abnormally.
tmpfile returns a pointer to the FILE object associated
with the temporary file (or NULL if the temporary file cannot
be created).
tmpfile function or
through the UNIX style I/O functions, vary with the operating system.
However,
tmpfile is portable unless a program depends on special properties of
"rel" files.
