SYNOPSIS
       #include 

       size_t strlen(const char *s);
DESCRIPTION
The strlen function returns the length of string s. It does not count the terminating null.
NOTES

Much like strdup, this str function is another case of code reuse and/or consolidation. It's easy enough to write your own code to find the length of a string (or assume, if you're lazy/stupid), but the library has it so you don't need to. A meat and potatoes function, you'll use it a lot if you deal with strings.
