PetscPushSignalHandler

Catches the usual fatal errors and calls a user-provided routine.

Synopsis

#include "petscsys.h"   
PetscErrorCode PetscPushSignalHandler(PetscErrorCode (*routine)(int, void *), void *ctx)

Not Collective

Input Parameters

• routine - routine to call when a signal is received

• ctx - optional context needed by the routine

Note

There is no way to return to a signal handler that was set directly by the user with the UNIX signal handler API or by the loader. That information is lost with the first call to PetscPushSignalHandler()
