InitializeSid

The InitializeSid function initializes a SID structure. An SID is a security identifier.

BOOL InitializeSid(
  PSID Sid,                 // address of SID to initialize
  PSID_IDENTIFIER_AUTHORITY pIdentifierAuthority,
                            // address of identifier authority
  BYTE nSubAuthorityCount   // count of subauthorities
);
 

Parameters

Sid

Pointer to a SID structure to be initialized.

pIdentifierAuthority

Pointer to a SID_IDENTIFIER_AUTHORITY structure to set in the SID structure.

nSubAuthorityCount

Specifies the number of subauthorities to set in the SID. Values of the subauthority must be set separately, as described in the following Remarks section.

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.

Remarks

Although the InitializeSid function sets the number of subauthorities for the SID, it does not set the subauthority values. This must be done separately, using functions, such as GetSidSubAuthority.

An application can use the AllocateAndInitializeSid function to initialize a SID and set its subauthority values.
