Amiga System Libraries Overview
This table lists the system libraries, devices and resources, along with a brief description of their function and version information. Full details of the use of the libraries can be found in the Amiga Reference manuals.
Points to note:
- Many libraries are commonly used on systems that initially didn't ship with them, e.g. GadTools is available for OS 1.x systems.
- Some libraries (e.g. exec.library) were part of the OS earlier than V33 (1.2), but 1.2 is considered as the first widely released version and is thus listed as the introduction date.
- Resources are specific to certain hardware, so their direct use should be avoided if compatibility with different systems is desired. Generally there's a higher level method of accessing the features that should be preferred, e.g. accessing battmem.resource will fail on machines with no non-volatile RAM, but using nonvolatile.library instead will instead redirect the calls to a disk-based resource on such machines.
- Some modules have significant changes between versions, so software written for later versions may not work, even if the library is present on earlier systems.
