EXAMPLES

   Creating a File
       The  following example creates the file /tmp/file with read and write permissions for the file owner and read permission for group and oth-
       ers. 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);
	      ...

APPLICATION USAGE

       None.

RATIONALE

       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.

FUTURE DIRECTIONS

       None.
