tmpfile(3S) tmpfile(3S)
NAME
tmpfile() - create a temporary file
SYNOPSIS
DESCRIPTION
creates a temporary file by generating a name through (see tmpnam(3S)), and returns a corresponding 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
Notes
On HP-UX systems, the mode is equivalent to the mode.
ERRORS
The 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 in this environment.
Additional values may be set by the underlying function (see fopen(3S)).
SEE ALSO
