PetscCalloc#
Allocates a cleared (zeroed) memory region aligned to PETSC_MEMALIGN, similar to PetscMalloc()
Synopsis#
#include <petscsys.h>
PetscErrorCode PetscCalloc(size_t m,void **result)
Not Collective
Input Parameter#
m - number of bytes to allocate
Output Parameter#
result - memory allocated
Notes#
Memory is always allocated at least double aligned. This macro is useful in allocating memory pointed by void pointers
It is safe to allocate with an m of 0 and pass the resulting pointer to PetscFree().
However, the pointer should never be dereferenced or the program will crash.
Developer Note#
All PetscCallocN() routines call PetscCalloc() behind the scenes.
