Návod, kniha: POSIX Programmer's Manual
#include <sys/stat.h>
#include <fcntl.h>
int creat(const char *
path, mode_t
mode );
The function call:
shall be equivalent to:
open(path, O_WRONLY|O_CREAT|O_TRUNC, mode)
Refer to
open() .

open() .
The following sections are informative.
The following example creates the file
/tmp/file with read and write
permissions for the file owner and read permission for group and others. The
resulting file descriptor is assigned to the
fd variable.
#include <fcntl.h>
...
int fd;
mode_t mode = S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH;
char *filename = "/tmp/file";
...
fd = creat(filename, mode);
...
None.
The
creat() function is redundant. Its services are also provided by the
open() function. It has been included primarily for historical purposes
since many existing applications depend on it. It is best considered a part of
the C binding rather than a function that should be provided in other
languages.
None.
