NAME¶

memzero_explicit - Fill a region of memory (e.g. sensitive keying data) with 0s.

SYNOPSIS¶

void memzero_explicit(void * s, size_t count);

ARGUMENTS¶

s

count

NOTE¶

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.
