InitializeSid function

The InitializeSid function initializes a security identifier (SID).

Syntax


BOOL WINAPI InitializeSid(
  _Out_  PSID Sid,
  _In_   PSID_IDENTIFIER_AUTHORITY pIdentifierAuthority,
  _In_   BYTE nSubAuthorityCount
);

Parameters

Sid [out]

A pointer to a SID structure to be initialized.

pIdentifierAuthority [in]

A pointer to a SID_IDENTIFIER_AUTHORITY structure to set in the SID structure.

nSubAuthorityCount [in]

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 value

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.

This function uses a 32-bit RID value. For applications that require a larger RID value, use CreateWellKnownSid.
