PETSc version 3.17.0
Fix/Edit manual page

# PetscMallocClear

Resets the routines used to do mallocs and frees to the defaults.

### Synopsis

    #include "petscsys.h"
    PetscErrorCode PetscMallocClear(void)

Not Collective

### Notes

In general one should never run a PETSc program with different malloc() and free() settings for different parts; this is because one NEVER wants to free() an address that was malloced by a different memory management system

Called in PetscFinalize() so that if PetscInitialize() is called again it starts with a fresh slate of allocation information
