Details
Declared functions
cleanup: Program exit
This function is called at the end of execution to clean up temporary files. It is installed on all exits that we might be able to capture.
killup: Signal handling This function is called in addition, if a signal has been caught. It prints the number of the signal and then runs cleanup.
newTmp: Get a new temporary file name.
Call this as
``cppnewTmp VARIABLE [EXTENSION]`
where EXTENSION is set to c if omitted. After the call, variable VARIABLE will be set to the result. ### newNumber: Get a new number that is unique for the same jobid Call this as
newNumber VARIABLE
After the call, variable VARIABLE will be set to the result. All places that use the same name VARIABLE will receive a different value during processing for the same job, even if they end up being in different sub-processes.
