Is there a clearer way to do the following? It tests
the beginning of a buffer for the word "begin ". I can't
use Instring here for various reasons...
;"begin " (lowercase)
.if byte ptr == 98 && byte ptr == 101 &&
byte ptr == 103 && byte ptr == 105 &&
byte ptr == 110 && byte ptr == 32
...
.endif
You can compare dwords, too.
;"begin " (lowercase)
.IF dword ptr ="igeb" && word ptr =" n"
....
.ENDIF
xtreme,
If its just the start of the buffer that you need to test, you
could use CMPSB to do the comparison. Means setting up a loop
but its simple enough code to write. All you do is have your
source string "begin " in a buffer and the string you wish to
test in a buffer, load them into ESI/EDI and do the comparison.
You use CMPSB with one of the REP prefixes and just set up the
test you require. If it matches CMPSB will read the length you
set in ECX, if not, it will exit on mismatch and you can test ECX
to check if it was a match or not.
