wait(3f)

Name
wait - waits for a process to terminate

Syntax
integer wait, retval, status
external wait
retval = wait ( status )

Description
The wait function causes its caller to be suspended until a signal is received or one of its child processes terminates. If any child process has terminated since the last call to wait, the return is immediate; if there are no children, the return of an error code is immediate.

If the return value is positive, it is the process ID of the child and status is its termination status (see wait(2) ). If the return value is negative, it is the negation of a system error code.
