создать временный файл (create a temporary file)
Имя (Name)
tmpfile - create a temporary file
Синопсис (Synopsis)
#include <stdio.h>
FILE *tmpfile(void);
Описание (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.
Возвращаемое значение (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.
Ошибки (Error)
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; see signal(7).
EMFILE The per-process limit on the number of open file
descriptors has been reached.
ENFILE The system-wide limit on the total number of open files
has been reached.
ENOSPC There was no room in the directory to add the new
filename.
EROFS Read-only filesystem.

Стандарты (Conforming to)
POSIX.1-2001, POSIX.1-2008, C89, C99, SVr4, 4.3BSD, SUSv2.
Примечание (Note)
POSIX.1-2001 specifies: 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, then the directory /tmp.
