pop Keyword

The pop keyword is used to pop STREAMS modules off the designated stream.

pop [module]

If pop is invoked with no arguments, the top module on the stream is popped. If an argument is given, modules are popped one at a time until the named module is at the top of the stream. If the named module is not on the designated stream, the stream is left as it was and the command fails. If module is the special keyword ALL, then all modules on the stream are popped. Note that only modules above the topmost driver are affected.
