waitpid PID,FLAGS Waits for a particular child process to terminate and returns the pid of the deceased process, or -1 if there is no such child process. On some systems, a value of 0 indicates that there are processes still running. The status is returned in $? and ${^CHILD_ERROR_NATIVE} . If you say use POSIX ":sys_wait_h"; #... do { $kid = waitpid(-1, WNOHANG); } while $kid > 0; then you can do a non-blocking wait for all pending zombie processes.

NAME DESCRIPTION SEE ALSO AUTHOR COPYRIGHT AND LICENSE NAME perlpodstyle - Perl POD style guide DESCRIPTION These are general guidelines for how to write POD documentation for Perl scripts and modules, based on general guidelines for writing good UNIX man pages. All of these guidelines are, of course, optional, but following them will make your documentation more consistent with other documentation on the system. The name of the program being documented is conventionally written in bold (usin

$< The real uid of this process. You can change both the real uid and the effective uid at the same time by using POSIX::setuid() . Since changes to $< require a system call, check $! after a change attempt to detect any possible errors. Mnemonic: it's the uid you came from, if you're running setuid.

${^POSTMATCH} This is similar to $' ($POSTMATCH ) except that it does not incur the performance penalty associated with that variable. See Performance issues above. In Perl v5.18 and earlier, it is only guaranteed to return a defined value when the pattern was compiled or executed with the /p modifier. In Perl v5.20, the /p modifier does nothing, so ${^POSTMATCH} does the same thing as $POSTMATCH . This variable was added in Perl v5.10.0. This variable is read-only and dynamically-scoped.
