mkfifo(3C) COMPATIBILITY FUNCTIONS mkfifo(3C)
NAME
mkfifo - create a new FIFO
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
int mkfifo (const char *path, mode_t mode);
DESCRIPTION
The mkfifo routine creates a new FIFO special file named by
the pathname pointed to by path. The mode of the new FIFO
is initialized from mode. The file permission bits of the
mode argument are modified by the process's file creation
mask [see umask(2)].
The FIFO's owner id is set to the process's effective user
id. The FIFO's group id is set to the process's effective
group id, or if the S_ISGID bit is set in the parent direc-
tory then the group id of the FIFO is inherited from the
parent.
mkfifo calls the system call mknod to make the file.
SEE ALSO
chmod(2), exec(2), mknod(2), umask(2), fs(4), stat(5).
mkdir(1) in the User's Reference Manual.
DIAGNOSTICS
Upon successful completion a value of 0 is returned. Other-
wise, a value of -1 is returned and errno is set to indicate
the error.
NOTES
Bits other than the file permission bits in mode are
ignored.
