[Sh4DoVV]

Hi friends

how to use SCSI_PASS_THROUGH_DIRECT structure in Masm ?

i want read disk structure with this structure

i have vb6 source , but i can not convert it to masm

 

[evlncrn8]

heres the ones i made in coding the parts in protection id

 

SCSI_PASS_THROUGH_DIRECT struct

    DataLength        USHORT ?
    ScsiStatus         UCHAR ?
    PathId             UCHAR ?
    TargetId        UCHAR ?
    Lun            UCHAR ?
    CdbLength        UCHAR ?
    SenseInfoLength        UCHAR ?
    DataIn            ULONG ?  ; defined as UCHAR - seems wrong.. make it ULONG - all fine...
    DataTransferLength    ULONG ?
    TimeOutValue        ULONG ?
    DataBuffer        PVOID ?
    SenseInfoOffset        ULONG ?
    Cdb            UCHAR 16 dup(?)

SCSI_PASS_THROUGH_DIRECT ENDS

to do what exactly ? spti layer covers a multitude of things.. if you just want to read a cd -> iso or something just use the createfile->readfile method, its much easier, and for the aspi stuff, unless you plan to cater for win 95 or so, forget it, its not worth the trouble
