Function mlock_key_bytes

nodedb-wal/src/secure_mem.rs:57–62

Public convenience wrapper for mlocking raw key bytes from `crypto.rs`. Locks `len` bytes starting at `ptr`. Best-effort: logs a warning on failure. No-op on non-Unix targets.

(ptr: *mut u8, len: usize)

/// Locks `len` bytes starting at `ptr`. Best-effort: logs a warning on failure.
