One of the following values:ValueAction< –1 Specifies to wait for any child process whose process group ID is equal to the absolutevalue of ipid.–1 Specifies to wait for any child process; this is the same behavior as PXFWAIT.0 Specifies to wait for any child process whose process group ID is equal to that of thecalling process.> 0 Specifies to wait for the child whose process ID is equal to the value of ipid.2-358
