DdeKeepStringHandle info  Overview  Group

The DdeKeepStringHandle function increments the usage count associated with the specified handle. This function enables an application to save a string handle passed to the application’s dynamic data exchange (DDE) callback function. Otherwise, a string handle passed to the callback function is deleted when the callback function returns. This function should also be used to keep a copy of a string handle referenced by the CONVINFO structure returned by the DdeQueryConvInfo function.

HSZ hsz	// handle to string
);

Parameters

Specifies the application instance identifier obtained by a previous call to the DdeInitialize function.

hsz

Return Values

If the function succeeds, the return value is nonzero.
