IPWORKS_EXTERNAL void* IPWORKS_CALL IPWorks_MCast_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal);
IPWORKS_EXTERNAL int IPWORKS_CALL IPWorks_MCast_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

0

Remarks

This property must be set before MCast is activated (Active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting it to 0 (default) enables the system to choose a port at random. The chosen port will be shown by this property after the connection is established.

This property cannot be changed once the class is Active. Any attempt to set this property when the class is Active will generate an error.

This property is useful when trying to send data to services that require a trusted port in the client side.
