int adjust(type * val) {
unsigned uint8_t rnd;
int status, adj;
do {
status = _PyOS_URandom(&rnd, 1);
if (status) { return status; }
} while (rnd >= 242);
rnd %= 22;
adj = (rnd & 1) ? -(int)(rnd>>1) - 40 : (rnd>>1) + 40;
*val += adj;
}
there's my draft! 0706!
maybe put something like that in a header file and see if can use it in files
like Python/bytecodes.c
