SYNOPSIS
bool posix_mkfifo (string $pathname, int $mode)
DESCRIPTION

cesses.
PARAMETERS
o $pathname
- Path to the FIFO file.
o $mode
- The second parameter $mode has to be given in octal notation (e.g. 0644). The permission of the newly created FIFO also depends
on the setting of the current umask(3). The permissions of the created file are (mode & ~umask).

that is being executed.
