NAME
     mkfifo - make a FIFO special file

SYNOPSIS
     mkfifo(path, mode)
     char *path;
     int mode;

DESCRIPTION
     mkfifo creates a FIFO special file whose name is pointed to by path. mode
     sets the mode of the new file, including the special file bits.  (The
     protection part of the mode is modified by the process' mode mask; see
     umask(2)).  The owner ID of the file is set to the effective user ID of
     the process.  The group ID of the file is set to the effective group ID
     of the process.

     mkfifo will fail if:

     [EACCESS]   A component of the path prefix denies search permission.

     [EIO]       An I/O error occurred while writing to the file system.

     [ENOTDIR]   A component of the path prefix is not a directory.

     [ENOENT]    A component of the path prefix does not exist.

     [EROFS]     The named file resides on a read-only file system.

     [EEXIST]    The named file exists.

     [EFAULT]    path points outside the process' allocated address space.
