SYNOPSYS

 #include "mut.h"
 int mbkwaitpid( pid, mode, status )
 int pid;
 int mode;
 int *status;
 

PARAMETER

pid

Process number to wait.

mode

If mode is set to 1, this function return only when the child process is terminated. Otherwise, function return immediatly.

status

If not NULL, the exit status of terminated child process.

DESCRIPTION

mbkwaitpid provides a centralized way to catch terminated child process. Because some Alliance library can create a child process, and user application can do so, there must be a centralized way to get the exit status of process. The programmer should never modify the handler for SIGCHLD.

RETURN VALUE

mbkwaitpid return 1 if child process is terminated, and 0 if isn't (case mode != 1 ).
