Sets the underlying allocation routines used by PetscMalloc() and PetscFree()

Synopsis#

#include "petscsys.h"   
PetscErrorCode PetscMallocSet(PetscErrorCode (*imalloc)(size_t, PetscBool, int, const char[], const char[], void **), PetscErrorCode (*ifree)(void *, int, const char[], const char[]), PetscErrorCode (*iralloc)(size_t, int, const char[], const char[], void **))

Not Collective

Input Parameters#

  • imalloc - the routine that provides the malloc() implementation (also provides calloc(), which is used depending on the second argument)

  • ifree - the routine that provides the free() implementation

  • iralloc - the routine that provides the realloc() implementation

Note#

This routine MUST be called before PetscInitialize() and may be called only once.
