Hi All,

can sombody explain why this is hanging at zwcreatefile call. Trying to
create a file from within driver.

HANDLE handle;
OBJECT_ATTRIBUTES InitializedAttributes;
IO_STATUS_BLOCK ioStatusBlock;
NTSTATUS ntStatus;
UNICODE_STRING uniFileName;

RtlInitUnicodeString(&uniFileName, L"\??\c:\Mydata.dat");

InitializeObjectAttributes(&InitializedAttributes,
&uniFileName,
OBJ_CASE_INSENSITIVE,
NULL,
NULL);

ntStatus = ZwCreateFile(&handle,
FILE_WRITE_DATA,
&InitializedAttributes,
&ioStatusBlock,
NULL,
FILE_ATTRIBUTE_NORMAL,
0,
FILE_OVERWRITE_IF,
FILE_NON_DIRECTORY_FILE,
NULL,
0);

TIA
-Fareed
