WAIT 3F ""
C 5 NAME
wait - wait for a process to terminate
SYNOPSIS
integer function wait (status) integer status
DESCRIPTION
Wait causes its caller to be suspended until a signal is received or one of
its child processes terminates.
If any child has terminated since the last
wait, return is immediate; if there are no children, return is immediate
with an error code.
If the returned value is positive, it is the process ID of the child and status is its termination status (see wait (2)). If the returned value is negative, it is the negation of a system error code.
