[pso] [tema5][win]creare IRP

[Mihnea Muraru]

Salut!

La tema 5 pe windows ma lovesc de urmatorul comportament:

Obtin mai intai device-ul asociat PhysicalDrive1, folosind
IoGetDeviceObjectPointer si trimitandu-i ca nume symlink-ul:


UNICODE_STRING devName, physName1, physName2;
PDEVICE_OBJECT physDev1, physDev2;
PFILE_OBJECT physFile1 = NULL, physFile2 = NULL;

RtlInitUnicodeString(&physName1, L"\\??\\PhysicalDrive1");
IoGetDeviceObjectPointer(&physName1, STANDARD_RIGHTS_ALL, &physFile1,
&physDev1);


Functia intoarce succes, dar, mai departe, IoBuildSynchronousFsdRequest
intoarce NULL (parametrii sunt initializati):


irp = IoBuildSynchronousFsdRequest(MajorFunction, physDev1, Buffer,
        Length, StartingOffset, &event, IoStatusBlock);


Am incercat de curiozitate sa trimit in loc de physDev1, insusi device-ul
inregistrat de driver (SoftwareRaid) si functia a reusit sa creeze pachetul.

Care ar putea fi problema?

Exista vreo functie asemanatoare GetLastError?
