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).
