The DdeImpersonateClient function impersonates a dynamic data exchange (DDE) client application in a DDE client conversation.
BOOL DdeImpersonateClient(
|
HCONV hConv |
// handle to DDE conversation |
|
); |
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.
Impersonation is the ability of a process to take on the security attributes of another process. When a client in a DDE conversation requests information from a DDE server, the server impersonates the client. When the server requests access to an object, the system verifies the access against the client’s security attributes.
When the impersonation is complete, the server normally calls the RevertToSelf function.
