Standard C Library Functions tmpfile(3C)
NAME
tmpfile - create a temporary file
SYNOPSIS
#include
FILE *tmpfile(void);
DESCRIPTION
The tmpfile() function creates a temporary file and opens a
corresponding stream. The file will automatically be
deleted when all references 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 offt will be established as the offset max-
imum 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.
ERORS
The tmpfile() function will fail if:
EINTR A signal was caught during the execution of
tmpfile().
EMFILE There are OPENMAX 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 FOPENMAX 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 pro-
cess 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).
