# PetscMalloc

Allocates memory

### Input Parameter

m -number of bytes to allocate

### Output Parameter

result -memory allocated

### Synopsis

    PetscErrorCode PetscMalloc(size_t m,void **result)

Notes: Memory is always allocated at least double aligned

If you request memory of zero size it will allocate no space and assign the pointer to 0; PetscFree() will properly handle not freeing the null pointer.
