PetscHelpPrintf

Prints help messages.

#include <petscsys.h>
PetscErrorCode (*PetscHelpPrintf)(MPI_Comm comm, const char format[],args);

Collective on comm

	comm	- the MPI communicator over which the help message is printed
	format	- the usual printf() format string
	args	- arguments to be printed

This routine is not supported in Fortran.

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(0);

} then do the assigment

   PetscHelpPrintf = mypetschelpprintf;

You can do the assignment before PetscInitialize().

The default routine used is called PetscHelpPrintfDefault().
