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 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);
              ...

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.
