Function Documentation

TCOD_strscpy()

static size_t TCOD_strscpy ( char * dest, const char * src, size_t count )

inlinestatic

Copy src into a fixed-size buffer, return bytes copied excluding NULL and always NULL terminates dest.

Safer and easier to understand than strncpy while also being faster.
