- void memzero_explicit(void * s, size_t count);
- Pointer to the start of the area.
- The size of the area.
usually using memset is just fine (!), but in cases where clearing out _local_ data at the end of a scope is necessary, memzero_explicit should be used instead in order to prevent the compiler from optimising away zeroing.
memzero_explicit doesn't need an arch-specific version as it just invokes the one of memset implicitly.
