In-Context Hook Functions

  • Makale

The following list outlines the key aspects of in-context hook functions:

  • In-context hooks functions must be located in a dynamic-link library (DLL) that the system maps into the server's address space.
  • In-context hook functions share the address space with the server.
  • When the server triggers an event, the system calls a hook function without marshaling (packaging and sending interface parameters across process boundaries).
  • In-context hook functions tend to be very fast and receive event notifications synchronously because there is no marshaling.
  • Some events may be delivered out-of-process, even though you request that they be delivered in-process (using the WINEVENT_INCONTEXT flag). You might see this situation with 64-bit and 32-bit application interoperability issues and with Windows console events.
