- Subject: obtaining process exit code from popen()

Has anybody worked out how to obtain the exit code from a sub-process
invoked using popen()?
It looks to me that the exit code is currently discarded b/c the
standard __close meta-method only returns a boolean.
Would it be possible to define an alternate close method (i.e.,
pclose()) which one could use to close a stream opened using popen() and
obtain the exit code from the sub-process? Has this already been done?
