What is inlining, and when might it be beneficial?

Why, in the following code, is the compiler unable to move the call to strlen out of the loop?

          void upper(char *s) {

               for (long i = 0; i < strlen(s);="" i++)="">

                    if (s[i] >= 'a' && s[i] <=>

                         s[i] += ('Z' - 'z');

               }

          }
