tmpﬁle(3S) tmpﬁle(3S)

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

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