DESCRIPTION¶
Returns the index of the first occurence of str2 in str searching from position pos (default: -1 == string end) on backward. In other words: the index of the last occurance of str2 before the given position pos.
The returned index is relative to the beginning of the string.
If str2 is not found in str, -1 is returned.
If pos is negative, it designates the start position relative to the end of the string (the search will still proceed towards the beginning of the string).
