RtlInitializeSid function

Description

The RtlInitializeSid routine initializes a security identifier (SID) structure.

Parameters

Sid [out]

Pointer to a caller-allocated SID structure to be initialized.

IdentifierAuthority [in]

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

SubAuthorityCount [in]

Number of subauthorities to set in the SID. Subauthority values must be set separately, as described in the following Remarks section.

Return value

RtlInitializeSid returns one of the following:

Return code Description
STATUS_SUCCESS The SID was successfully initialized.
STATUS_INVALID_PARAMETER The specified SubAuthorityCount value is invalid.

Remarks

Although RtlInitializeSid sets the number of subauthorities for the SID, it does not set the subauthority values. This must be done separately by calling RtlSubAuthoritySid.

For more information about security and access control, see Windows security model for driver developers and the documentation on these topics in the Windows SDK.
