How to convert ULONG to String at <= DISPATCH_LEVEL

NTFSD
1

Hi,

I have a ULONG variable that I want to convert to a string value. In user
space I’d use ultoa. However, I’d like to develop this conversion in kernel
mode at <= DISPATCH_LEVEL. Is there a function that I can use to do this or
do I need to create my own function?

Thanks,

Marc

Why not look in any college textbook where data conversion of this type is discussed?

RtlIntegerToUnicodeString or RtlIntPtrToUnicodeString

NOTE they only work at passive level.

I think the ansi string or unicode string encode as sequencely this means
‘0’ + 9 = ‘9’ ,
i think we could write some trick code for deal this.
