Search for substrings in a string.
int strsrch( string str, string substr | int char, int flag );
strsrch() searches for the first occurance of the string ‘substr’ in the string ‘str’. The last occurance of ‘substr’ can be found by passing ‘-1’ as the 3rd argument (which is optional). If the second argument is an integer, that character is found (like C’s strchr()/strrchr().) The empty string or null value cannot be searched for.
The integer offset of the first (last) match is returned. -1 is returned if there was no match, or an error occurred (bad args, etc).
