MorphOS API and Its Organization

Grzegorz Kraszewski

An Application Programmer Interface of an operating system consists of thousands of functions usually. MorphOS is no exception here. Its kernel is not monolithic however. The API is functionally (and physically) divided into libraries. Only a few largest libraries contain more than 50 functions. A core set of most important libraries is contained in the system boot image. The rest is placed on the system partition in MOSSYS:Libs (libraries delivered with the system) and SYS:Libs (third party libraries) directories. Disk based libraries are loaded on demand. All these libraries are shared, it means all processes using a library execute the same code loaded to memory once.
