How do I close a file descriptor by number?
This should rarely be necessary, as the Perl close() function is to be used for things that Perl opened itself, even if it was a dup of a numeric descriptor, as with MHCONTEXT above. But if you really have to, you may be able to do this: require 'sys/syscall.ph';
$rc = syscall(&SYS_close, $fd + 0); # must force numeric
die "can't sysclose $fd: $!" unless $rc == -1; |
