Detailed Description
Synopsis
This C++ library defines the device driver API, the message queues used to move messages between devices, facilities for parsing configuration files and for loading and instantiating drivers.The primary components of libplayercore are:
- Messaging basics : The basics of Player-based messaging, including size limits, unit specifications, and address structures.
- Interface specifications : The syntax and semantics of all the messages for each Player interface.
- ConfigFile : Configuration file parsing
- Message : The basic object used to transfer information
- MessageQueue : Messages are delivered by being pushed onto queues; every driver has one
- Driver : The class from which all drivers inherit
- Device : An instantied driver that is bound to an interface; all external access to a driver is mediated through one or more Device objects
Example compilation and linkage
The most common usage of libplayercore is in building a plugin driver. If the code for your driver is in mydriver.cc, you can build it like this (on Linux):$ g++ `pkg-config --cflags playercore` -o -shared mydriver.so mydriver.cc `pkg-config --libs playercore`
