Name
tmpfile — create a temporary file
DESCRIPTION
The tmpfile
() function opens
a unique temporary file in binary read/write (w+b) mode. The
file will be automatically deleted when it is closed or the
program terminates.
RETURN VALUE
The tmpfile
() function
returns a stream descriptor, or NULL if a unique filename
cannot be generated or the unique file cannot be opened. In
the latter case, errno
is set to
indicate the error.
ERRORS
- EACCES
-
Search permission denied for directory in file's
path prefix.
- EEXIST
-
Unable to generate a unique filename.
- EINTR
-
The call was interrupted by a signal.
- EMFILE
-
Too many file descriptors in use by the process.
- ENFILE
-
Too many files open in the system.
- ENOSPC
-
There was no room in the directory to add the new
filename.
- EROFS
-
Read-only filesystem.
CONFORMING TO
SVr4, 4.3BSD, C89, C99, SUSv2, POSIX.1-2001.
NOTES
An error message may be written to stdout
if the stream cannot be opened.
The standard does not specify the directory that
tmpfile
() will use. Glibc will
try the path prefix P_tmpdir
defined in
<stdio.h>
,
and if that fails the directory /tmp
.
