Why the 'strstr' will cause the system dump?

NTDEV
1

I amend the passthru but it cause the system dump.
I open the crash memory file and the windbg shows a error occur when the program excute the ‘strstr’.The
source code is " pdest = strstr( DnsName, “HTTP” );",The ‘DnsName’ is defined as ‘char DnsName[200]’

Is there any function in ddk can replace the ‘strstr’?

And how can I see the varible’s value in windbg ?

2

Strstr sources are in the CRTL source code

Use the NTSTRSAFE.H header file and look at the documentation in VS .Net 2003 and build 3790 of the DDK for Safe String operations. I also have an article in May issue of www.Wd-3.com that might help.

He means that this function is from the ‘C’ Runtime Library (CRTL), which is not part of the kernel-mode API.

Read about the Rtl and RtlString functions in the DDK.
