libcomm Description

libcomm's purpose of this library is to facilitate handling structured messages between programs. libcomm's purpose of this library is to facilitate handling structured messages between programs. The messages consist of three parts: a keyword, a body and a delimiter.The delimiter denotes the end of the message. Examples of a delimiter can be a simple newline ("n") for single line messages, or a double ("nn") newline for multi-line messages.The keyword is used to identify the message. In the receiving program, it is used to dispatch the body to a handler function.The body is everything between the keyword and the delimiter.An example of the usage of this library might be to facilitate the communication between a GUI frontend and a program doing calculations in the background (the "backend").Since the messages are human-readable (as opposed to shared memory or binary messages), it would enable the backend to be tested separately from the frontend, either by a human or by a testing script.BUILDING THE LIBRARYInvoking the "make" command gives you a list of all possible options.The usual invocation for a system-wide installation of the library would be to do "make all", "make test", login as root, and then do a "make install".Alternatively you can embed the library in your own program, by sticking it into a subdirectory, and invoking "make static" there.USING THE LIBRARYSee the manual pages launch_program.3 and kill_program.3 on how to use thefunctions.
