NAME

tmpfile() − create a temporary file

SYNOPSIS

#include <stdio.h>

FILE *tmpfile(void);

DESCRIPTION

tmpfile() creates a temporary file by generating a name through tmpnam() (see tmpnam(3S)), and returns a corresponding FILE pointer.  If the file cannot be opened a NULL pointer is returned.  The file is automatically deleted when the process using it terminates.  The file is opened for update (wb+). 

ERRORS

The tmpfile() function will fail if:

[EOVERFLOW] The named file is a regular file and the size of the file cannot be represented correctly in an object of size off_t in this environment. 

Additional errno values may be set by the underlying fopen() function (see fopen(3S)).

NOTES

On HP-UX systems, the wb+ mode is equivalent to the w+ mode.
