Descriptions of the Library Routines 2istat(Output) INTEGER(4). The returned status of the child process.ioptions(Input) INTEGER(4). One or more of the following constant values (which can be passed toPXFCONST or IPXFCONST):ValueWNOHANGWUNTRACEDActionSpecifies to return immediately if no child process has exited.Specifies to return for child processes that have stopped, and whose statushas not been reported.iretpid(Output) INTEGER(4). The PID of the stopped child process.ierror(Output) INTEGER(4). The error status.If successful, ierror is set to zero; otherwise, an error code.The PXFWAITPID subroutine suspends execution of the current process until the child specifiedby ipid has exited, or until a signal is delivered whose action terminates the current process or callsa signal handling routine. If the child specified by ipid has already exited by the time of the call (a"zombie" process), a return is immediately made. Any system resources used by the child arefreed.The returned value in istat can be used in subroutines IPXFWEXITSTATUS, IPXFWSTOPSIG,IPXFWTERMSIG, PXFWIFEXITED, PXFWIFSIGNALLED, and PXFWIFSTOPPED.See Also: “PXFWAIT”, “IPXFWEXITSTATUS”, “IPXFWSTOPSIG”, “IPXFWTERMSIG”,“PXFWIFEXITED”, “PXFWIFSIGNALED”, “PXFWIFSTOPPED”PXFWIFEXITEDPOSIX Function: Determines if a child process has exited. This subroutine is only available onLinux* systems.Module: USE IFPOSIXSyntaxresult = PXFWIFEXITED (istat)2-359
