### NAME

    strsrch() - search for substrings in a string

### SYNOPSIS

    int strsrch( string str, string substr | int char,
                 int flag );

### DESCRIPTION

    strsrch()  searches  for  the first occurance of the string 'substr' in
    the string 'str'.  The last occurance of 'substr' can be found by pass‐
    ing  '-1' as the 3rd argument (which is optional).  If the second argu‐
    ment is an integer, that character is found  (a  la  C's  strchr()/str‐
    rchr().)  The empty string or null value cannot be searched for.

### RETURN VALUE

    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).
