Detailed Description

Used internally by OProcess.

For internal use only.

Author:

Christian Czezakte <e9025461@student.tuwien.ac.at>

A class for internal use by OProcess only. -- Exactly one instance of this class is generated by the first instance of OProcess that is created (a pointer to it gets stored in theOProcessController ).

This class takes care of the actual (UN*X) signal handling.

void OProcessController::theSigCHLDHandler (  int  signal  )  [static]

Automatically called upon SIGCHLD. Normally you do not need to do anything with this function but if your application needs to disable SIGCHLD for some time for reasons beyond your control, you should call this function afterwards to make sure that no SIGCHLDs where missed.

Referenced by setupHandlers().
