PetscMalloc

Allocates memory, One should use PetscNew(), PetscMalloc1() or PetscCalloc1() usually instead of this

#include <petscsys.h>
PetscErrorCode PetscMalloc(size_t m,void **result)

Not Collective

m -number of bytes to allocate

result -memory allocated

Memory is always allocated at least double aligned

It is safe to allocate size 0 and pass the resulting pointer (which may or may not be NULL) to PetscFree().
