I've got a char array and I'm not sure how to send one of the characters in it to atoi properly. Anybody know how?

???char hex[MAX];

???result += (ret2 = atoi(?????)) * (ret = pow(16, i));

EDIT: would this be corrent?

???char hex[MAX];

???result += (ret2 = atoi(&hex[i])) * (ret = pow(16, i));

that passes the address.

result += (ret2 = atoi(hex[i])) * (ret = pow(16, i));

if its a hex number you want to use atoul not atoi or look into strtoul which can read ascii-hex into numeric.
