CopySid info  Overview  Group

The CopySid function copies a security identifier (SID) to a buffer.

BOOL CopySid(

DWORD nDestinationSidLength,	// size of buffer for copied SID
PSID pDestinationSid,	// pointer to buffer for copied SID
PSID pSourceSid	// pointer to source SID
);

Parameters

nDestinationSidLength

Specifies the length, in bytes, of the buffer receiving the copy of the SID.

pDestinationSid

Points to a buffer receiving a copy of the source SID structure.

pSourceSid

Points to a SID structure the function copies to the buffer pointed to by the pDestinationSid parameter.
