API functions

The PicoScope 4000 Series API exports the following functions for you to use in your

own applications. All functions are C functions using the standard call naming

convention (__stdcall). They are all exported with both decorated and undecorated

names.

ps4000BlockReady: receive notification when block-mode data ready
