Assuming that you mean an exact match and also assuming you aren't writing 
in 'C' or 'C++' where you would have 'strstr()' available...

Try looking in Robert Sedgewick's book "Algorithms".  I implemented the
Zortech library's strstr() from this book (with some tweaks for more speed)
and it compared quite favorably to several other versions of strstr() that
I had obtained for comparision.
