I think the problem with strcspn is that it is not being used correctly. If you want to see if a string consists of numbers and only numbers, use strspn instead of strcspn like this:
{{{
/ teststring must be properly null terminated /
size_t end = strspn(teststring, "0123456789");
if (end && (teststring[end] == '\0')) { / end is the index of the trailing \0 /
/ string consists of only numbers /
} else {
/ string has characters other than numbers in it /
}
}}}
Basically, use strspn when you want a string to have only the specified characters, and use strcspn when you want a string that has none of the specified characters.

Thanks for the insight! I was thrown off because strcspn was working when just dealing with numbers and letters, but it did not work with other characters. Using strspn() worked for all the cases.

New patch attached.
