// ============================= LOCAL FUNCTIONS ===============================

// -----------------------------------------------------------------------------

// Funcation name: mkfifo

// Description: Provides a FIFO special file (a named pipe).

// Returns: 0     : On success

//          -1    : On error

// In case of error, errno value set to

//          EACCES: One  of  the  directories in pathname did not allow search

//                  (exe-cute) permission.

//          EEXIST: pathname already exists.

//          ENAMETOOLONG: Either the total length of pathname is greater

//                        than PATH_MAX, or an individual  file  name  component

//                        has a length greater than NAME_MAX.  In the GNU system,

//                        there is no imposed limit on over-all  file name length,

//                        but some file systems may place limits on the length of a component.

//          ENOENT: A directory component in pathname does not exist or  is  a  dan-gling

//                  symbolic link.

//          ENOSPC: The directory or filesystem has no room for the new file.

//          ENOTDIR: A  component  used as a directory in pathname is not, in fact, a

//                   directory.

//          EROFS:  pathname refers to a read-only filesystem.

// To be removed

//          EFAULT: Pathname is not valid.

//          EMFILE: Too many file descriptors are in use by the process.

//          ENFILE: System limit on the total number of open files has been

//                  reached.
