// pointer to identifier authority

    BYTE nSubAuthorityCount,

// count of subauthorities

    DWORD dwSubAuthority0,

// subauthority 0

    DWORD dwSubAuthority1,

// subauthority 1

    DWORD dwSubAuthority2,

// subauthority 2

    DWORD dwSubAuthority3,

// subauthority 3

    DWORD dwSubAuthority4,

// subauthority 4

    DWORD dwSubAuthority5,

// subauthority 5

    DWORD dwSubAuthority6,

// subauthority 6

    DWORD dwSubAuthority7,

// subauthority 7

    PSID *pSid 

// pointer to pointer to SID



Pointer to an SID_IDENTIFIER_AUTHORITY structure, giving the top-level identifier authority value to set in the SID.
Specifies the number of subauthorities to place in the SID. This parameter also identifies how many of the subauthority parameters have meaningful values. This parameter must contain a value from 1 through 8.

For example, a value of 3 indicates that the subauthority values specified by the dwSubAuthority0, dwSubAuthority1, and dwSubAuthority2 parameters have meaningful values and to ignore the remainder.

dwSubAuthority0 through dwSubAuthority7
Specify subauthority values to place in the SID.
Pointer to a variable that receives the pointer to the allocated and initialized SID structure.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


An SID allocated with the AllocateAndInitializeSid function must be freed by using the FreeSid function.
