EqualSid function (securitybaseapi.h)

The EqualSid function tests two security identifier (SID) values for equality. Two SIDs must match exactly to be considered equal.

Syntax

BOOL EqualSid(
  [in] PSID pSid1,
  [in] PSID pSid2
);

Parameters

[in] pSid1

A pointer to the first SID structure to compare. This structure is assumed to be valid.

[in] pSid2

A pointer to the second SID structure to compare. This structure is assumed to be valid.

Return value

If the SID structures are equal, the return value is nonzero.

If the SID structures are not equal, the return value is zero. To get extended error information, call GetLastError.

If either SID structure is not valid, the return value is undefined.
