* Name: wait
|
|
*
|
|
* Description:
|
|
* The wait() function will suspend execution of the calling thread until
|
|
* status information for one of its terminated child processes is
|
|
* available, or until delivery of a signal whose action is either to
|
|
* execute a signal-catching function or to terminate the process. If more
|
|
* than one thread is suspended in wait() or waitpid() awaiting termination
|
|
* of the same process, exactly one thread will return the process status
|
|
* at the time of the target process termination. If status information is
|
|
* available prior to the call to wait(), return will be immediate.
|
|
*
|
|
* The waitpid() function will behave identically to wait(), if the pid
|
|
* argument is INVALID_PROCESS_ID and the options argument is 0. Otherwise,
|
|
* its behaviour will be modified by the values of the pid and options
|
|
* arguments.
|
|
*
|
|
* Input Parameters:
|
|
* stat_loc - The location to return the exit status
|
|
*
|
|
* Returned Value:
|
|
* See waitpid();
|
|
