The DuplicateToken function creates a new access token that duplicates one already in existence.
BOOL DuplicateToken(
| HANDLE ExistingTokenHandle, | // handle to token to duplicate |
| SECURITY_IMPERSONATION_LEVEL ImpersonationLevel, | // impersonation level |
| PHANDLE DuplicateTokenHandle | // handle to duplicated token |
| ); |
Parameters
ExistingTokenHandle
Identifies an access token opened with TOKEN_DUPLICATE access.
ImpersonationLevel
Specifies a SECURITY_IMPERSONATION_LEVEL enumerated type that supplies the impersonation level of the new token.
DuplicateTokenHandle
Pointer to a variable that receives the handle of the duplicate token. This handle has TOKEN_IMPERSONATE and TOKEN_QUERY access to the new token.
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
The DuplicateToken function creates an impersonation token, which you can use in functions such as SetThreadToken and ImpersonateLoggedOnUser. The token created by DuplicateToken cannot be used in the CreateProcessAsUser function, which requires a primary token. To create a token that you can pass to CreateProcessAsUser, use the DuplicateTokenEx function.
