Sure, I guess the while loop is better than the for loop. The patch
description sucks. Move the len = 0 next to the code which uses len.
Fix the indenting. Use '\0' instead of 0 for characters.
Something like:
len = 0;
while (str[len] != '\0' && !isspace(str[len]) &&
str[len] != '+' && str[len] != '-')
len++;
