NAME
snobol4fork - POSIX fork for SNOBOL4

SYNOPSYS
    -INCLUDE 'fork.sno'

            pid = FORK()

            status = WAITPID([pid][,options])

            pid = GETPID()

            parent = GETPPID()

DESCRIPTION

FORK() creates a process: returns 0 in child, process ID in parent. WAITPID() takes an optional process id to wait for, and returns a string with the process id, status, and additional status about the child. options is a string of optional flags (see the waitpid(2) man page for details):

c   WCONTINUED

h   WNOHANG

t   WTRAPPED

u   WUNTRACED

w   NOWAIT

GETPID() returns the current process ID. It never fails.

GETPPID() returns the parent process ID. It never fails.
