PetscHelpPrintf#
Prints help messages.
Synopsis#
#include <petscsys.h>
PetscErrorCode (*PetscHelpPrintf)(MPI_Comm comm, const char format[],args);
Not Collective, only applies on MPI rank 0; No Fortran Support
Input Parameters#
comm - the MPI communicator over which the help message is printed
format - the usual printf() format string
args - arguments to be printed
Notes#
You can change how help messages are printed by replacing the function pointer with a function that does not simply write to stdout.
To use, write your own function, for example,
PetscErrorCode mypetschelpprintf(MPI_Comm comm,const char format[],....)
{
PetscFunctionReturn(PETSC_SUCCESS);
}
then do the assignment
PetscHelpPrintf = mypetschelpprintf;
You can do the assignment before PetscInitialize().
The default routine used is called PetscHelpPrintfDefault().
