Not quite. You would probably want the following semantics (probably implemented more efficiently):

const char *match;

if (strlen(str) <= startpos)
    return -1;

match = strstr(str + startpos, str_to_find);

if (!match)
    return -1;

return match-str;

which would indeed justify wrapping it in a call.

These would also be more convenient if they checked that the string you are trying to copy is long enough, again justifying the respective
call.
