tmpfile(3)              Library Functions Manual              tmpfile(3)

ИМЯ

       tmpfile - create a temporary file

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <stdio.h>

       FILE *tmpfile(void);

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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

       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.

ВЕРСИИ

       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.

СТАНДАРТЫ

       C11, POSIX.1-2008.

ИСТОРИЯ

       POSIX.1-2001, C89, SVr4, 4.3BSD, SUSv2.

ПРИМЕЧАНИЯ

       POSIX.1-2001 specifies: an error message may be written to stdout
       if the stream cannot be opened.
