tmpfile
tmpfile(3C) Standard C Library Functions tmpfile(3C)NAME
tmpfile - create a temporary file
SYNOPSIS
#include <stdio.h>
FILE *tmpfile(void);
DESCRIPTION
The tmpfile() function creates a temporary file and opens a corresponding stream. The file will automatically be deleted when all refer-
ences to the file are closed. The file is opened as in fopen(3C) for update (w+).
The largest value that can be represented correctly in an object of type off_t will be established as the offset maximum in the open file
description.
RETURN VALUES
Upon successful completion, tmpfile() returns a pointer to the stream of the file that is created. Otherwise, it returns a null pointer and
sets errno to indicate the error.
ERRORS
The tmpfile() function will fail if:
EINTR A signal was caught during the execution of tmpfile().
EMFILE There are OPEN_MAX file descriptors currently open in the calling process.
ENFILE The maximum allowable number of files is currently open in the system.
ENOSPC The directory or file system which would contain the new file cannot be expanded.
The tmpfile() function may fail if:
EMFILE There are FOPEN_MAX streams currently open in the calling process.
ENOMEM Insufficient storage space is available.
USAGE
The stream refers to a file which is unlinked. If the process is killed in the period between file creation and unlinking, a permanent
file may be left behind.
The tmpfile() function has a transitional interface for 64-bit file offsets. See lf64(5).
