C++ (Cpp) buffer_ensure_free Beispiele

Beispiel #1

int buffer_append(buffer *b, const void *m, size_t len) {
    int err;

    if (err = buffer_ensure_free(b, len), ERR_None != err) {
        return err;
    }

    memcpy((char *) b->buf + b->used, m, len);
    b->used += len;
    return ERR_None;
}

Beispiel #2

    int err;

    if ( used > b->used ) {

             buffer_ensure_free( b, used - b->used ), ERR_None != err ) {
            return err;
        }
    }

    b->used = used;
