# PetscMalloc
Allocates memory, One should use `PetscNew()`, `PetscMalloc1()` or `PetscCalloc1()` usually instead of this 
## Synopsis
```
#include <petscsys.h>
PetscErrorCode PetscMalloc(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

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


## See Also
 `PetscFree()`, `PetscNew()`
