MiNT Kernel System Calls

(as of 1998, needs updating)

The following function lists are originally produced by Yes Crew in 1998. The tables they provide with revision 26 (which can be found on this page), are the basis for the documentation provided below. Their documentation will be referenced, but not copied. Each function should also contain an example of use, preferably in Assembler as well as C or C++. The C calling convention should be noted as well, however at the time of writing, only GCC successfully compiles the MiNT kernel.

When an up to date list is completed, the contents will be made available, should anyone in Yes Crew wish to also update there documentation.
