The mouse reference is a pointer. If it's NULL, the driver uses a default. If it's non-NULL, then it points to a function that the driver can call. That function will adjust the driver's calibration value. It could ask the user to adjust the pen; or, it could read a file that holds a value from a previous calibration. Application writers can choose how it's done: a function that's provided by the library, a custom function, or nothing. |

cc65 is a complete cross development package for 65(C)02 systems, including
a powerful macro assembler, a C compiler, linker, librarian and several
other tools.
cc65 has C and runtime library support for many of the old 6502 machines,
including
- the following Commodore machines:
VIC20
C16/C116 and Plus/4
C64
C128
CBM 510 (aka P500)
the 600/700 family
newer PET machines (not 2001).
- the Apple ][+ and successors.
- the Atari 8 bit machines.
- GEOS for the C64 and C128.
- the Nintendo Entertainment System (NES).
- the Supervision console.
- the Oric Atmos.
- the Lynx console.
The libraries are fairly portable, so creating a version for other 6502s
shouldn't be too much work.
