String comparison

NTDEV
1

Hi,

Again a question on strings.
I want to compare 2 strings (char * and not PSTRING).

But I am facing following problems:

  1. memicmp and stricmp are not suggested to be used in drivers.
  2. The function RtlCompareString works on PSTRING.

I didn’t find any other function to do this task. Do I have to write my own
function ?
Or, is there any other method ?

TIA
Abhijit

Gregory

If you already know their lengths you could build STRING structures for
each and call RtlCompareString.

Alternately you could use the safe string functions (Windows
DDK\Kernel-Mode Driver Architecture\Reference\Driver Support
Routines\Safe String Functions in the ddk documentation)
