|
HCONV hConv |
// handle to DDE
conversation |
|
); |
|
Parameters
hConv
Identifies
the DDE client conversation to be impersonated.

function succeeds, the return value is nonzero.
If the

Remarks
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.
