Fclose

[Axel Kaiser <Axel.Kaiser@rz.ruhr-uni-bochum.de>]

Hi,

here is a, as I fear, silly question. When oppening a pipe
and using its handle for redirecting the standard handles,
what is the exact effect of closing the handle of the pipe?
Is it useful/necessary/forbidden to close the handle before
exec-uting a child process? 

Best regards
