PetscLogHandlerCreate#
Create a log handler for profiling events and stages. PETSc provides several implementations of PetscLogHandler that interface to different ways to summarize or visualize profiling data: see PetscLogHandlerType for a list.

#include "petscsys.h"
PetscErrorCode PetscLogHandlerCreate(MPI_Comm comm, PetscLogHandler *handler)
Collective
Input Parameter#
comm - the communicator for synchronizing and viewing events with this handler
Output Parameter#
