PXFWAITPID
POSIX Subroutine: Waits for a specific PID. This routine is only available for Linux and macOS.
Module
USE IFPOSIX
CALL PXFWAITPID (ipid,istat,ioptions,iretpid,ierror)
ipid |
(Input) INTEGER(4). The PID to wait for. One of the following values:
|
||||||||||
istat |
(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 to PXFCONST or IPXFCONST):
|
||||||||||
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 specified by ipid has exited, or until a signal is delivered whose action terminates the current process or calls a 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 are freed.
The returned value in istat can be used in subroutines IPXFWEXITSTATUS, IPXFWSTOPSIG, IPXFWTERMSIG, PXFWIFEXITED, PXFWIFSIGNALLED, and PXFWIFSTOPPED.
