zwcreatefile in IRP_MJ_CREATE!!??

OSR_Community_User · July 25, 2004, 11:44am

Hi,

Iam trying to open a file(by using ZwCreateFile) in

IRP_MJ_CREATE, but it

blue screens.

Is it not possible to open a file in IRP_MJ_CREATE?

Does native calls like ZwCreateFile results in recursive IRP_MJ_CREATE??

With Regards,
A.Ilamparithi

Hi,

This is the code sample i used.

swprintf( loggerPath, L"\Device\HarddiskVolume1\glDriver_logger.txt");

RtlInitUnicodeString( &fileName, loggerPath );
InitializeObjectAttributes(&ObjectAttributes, &fileName,
OBJ_CASE_INSENSITIVE,
NULL, NULL);

Status =
ZwCreateFile(&fileHandle,GENERIC_WRITE,&ObjectAttributes,
&IoStatusBlock,NULL,FILE_ATTRIBUTE_NORMAL,0,
FILE_CREATE,FILE_SYNCHRONOUS_IO_NONALERT,NULL,0);

if ( NT_SUCCESS( Status ) )
{
file://Close opened file and signal that we can log.
DbgPrint(“File Opened successfully”);
Status=ZwClose( fileHandle );
if(NT_SUCCESS(Status))
{
DbgPrint(“File Closed Successfully”);
}
}
else
{
if(IoStatusBlock.Information ==FILE_CREATED)
DbgPrint(“File Created”);
else if(IoStatusBlock.Information ==FILE_OPENED)
DbgPrint(“File opened”);
else if(IoStatusBlock.Information ==FILE_OVERWRITTEN)
DbgPrint(“File Written”);
else if(IoStatusBlock.Information ==FILE_SUPERSEDED)
DbgPrint(“File superseed”);
else if(IoStatusBlock.Information ==FILE_EXISTS)
DbgPrint(“File exist”);
else if(IoStatusBlock.Information ==FILE_DOES_NOT_EXIST)
DbgPrint(“File not exist”);
else
DbgPrint(“UNKNOWN return value”);
}

It works correctly when i try this with my IOCTL.

But when i try to do this in IRP_MJ_CREATE it blue screens.

I get unexcepted_kernel_mode_trap.

The trap number is sometimes 0x00000005 or 0x00000008.

With Thanks,
A.Ilamparithi.
