-Tcl_DetachPids, Tcl_ReapDetachedProcs, Tcl_WaitPid \- manage child processes in background

-.AS Tcl_Pid *statusPtr out
-.AP int numPids in
-Number of process ids contained in the array pointed to by \fIpidPtr\fR.
-.AP int *pidPtr in
-Address of array containing \fInumPids\fR process ids.
-.AP Tcl_Pid pid in
-The id of the process (pipe) to wait for.
-.AP int *statusPtr out
-The result of waiting on a process (pipe). Either 0 or ECHILD.

-The options controlling the wait. WNOHANG specifies not to wait when
-checking the process.
-.BE
-.SH DESCRIPTION
-.PP
-\fBTcl_DetachPids\fR and \fBTcl_ReapDetachedProcs\fR provide a
-mechanism for managing subprocesses that are running in background.
-These procedures are needed because the parent of a process must
-eventually invoke the \fBwaitpid\fR kernel call (or one of a few other
-similar kernel calls) to wait for the child to exit.  Until the
-parent waits for the child, the child's state cannot be completely
-reclaimed by the system.  If a parent continually creates children
-and doesn't wait on them, the system's process table will eventually
-overflow, even if all the children have exited.
-.PP
-\fBTcl_DetachPids\fR may be called to ask Tcl to take responsibility
-for one or more processes whose process ids are contained in the
-\fIpidPtr\fR array passed as argument.  The caller presumably
-has started these processes running in background and does not
-want to have to deal with them again.
-.PP
-\fBTcl_ReapDetachedProcs\fR invokes the \fBwaitpid\fR kernel call
-on each of the background processes so that its state can be cleaned
-up if it has exited.  If the process has not exited yet,
-\fBTcl_ReapDetachedProcs\fR does not wait for it to exit;  it will check again
-the next time it is invoked.
-Tcl automatically calls \fBTcl_ReapDetachedProcs\fR each time the
-\fBexec\fR command is executed, so in most cases it is not necessary
-for any code outside of Tcl to invoke \fBTcl_ReapDetachedProcs\fR.
-However, if you call \fBTcl_DetachPids\fR in situations where the
-\fBexec\fR command may never get executed, you may wish to call
-\fBTcl_ReapDetachedProcs\fR from time to time so that background
-processes can be cleaned up.
-.PP
-\fBTcl_WaitPid\fR is a thin wrapper around the facilities provided by
-the operating system to wait on the end of a spawned process and to
-check a whether spawned process is still running. It is used by
-\fBTcl_ReapDetachedProcs\fR and the channel system to portably access
-the operating system.
