PetscMalloc1#
Allocates an array of memory aligned to PETSC_MEMALIGN
Synopsis#
#include <petscsys.h>
PetscErrorCode PetscMalloc1(size_t m1,type **r1)
Not Collective
Input Parameter#
m1 - number of elements to allocate (may be zero)
Output Parameter#
r1 - memory allocated
Note#
This uses the sizeof() of the memory type requested to determine the total memory to be allocated, therefore you should not
multiply the number of elements requested by the sizeof() the type. For example use
PetscInt *id;
PetscMalloc1(10,&id);
not
PetscInt *id;
PetscMalloc1(10*sizeof(PetscInt),&id);
Does not zero the memory allocated, use PetscCalloc1() to obtain memory that has been zeroed.
