API Sources Tools File Format Technicals Type definitions [emu68 library documentation.] Detailed Description Definition of types used by EMU68 and SC68 related projects. Some of them are probably not neccessary and should be remove to improve execution time on 64 or more bit platforms. Setting wrong types may probably produce annoying effects on EMU68. It is a limitation to EMU68 portability. Files file   struct68.h   Struture definitions. file   type68.h   Type definitions header. Data Structures struct   int68_t   68K interruption exception structure. More... struct   _io68_t   IO emulator plugin structure. More... struct   reg68_t   68K emulator registers, memory and IO. More... Memory access caller type typedef u32(*  memrfunc68_t )(u32 addr, cycle68_t cycle)   Read memory function. typedef void(*  memwfunc68_t )(u32 addr, u32 value, cycle68_t cycle)   Write memory function. Fixed size integer types. typedef unsigned char  u8   Must be an unsigned 8 bit integer. typedef signed char  s8   Must be an signed 8 bit integer. typedef unsigned short  u16   Must be an unsigned 16 bit integer. typedef signed short  s16   Must be an signed 16 bit integer. typedef unsigned int  u32   Must be an unsigned 32 bit integer. typedef signed int  s32   Must be an signed 32 bit integer. typedef unsigned long long  u64   Must be an unsigned 64 bit integer. typedef signed long long  s64   Must be an signed 64 bit integer. Defines #define  IO68_NO_INT   (0x80000000)   IO no pending interruption return value. #define  NULL   0L   Default NULL constant. #define  MEM68MSK   ((1<<19)-1)   Mask for memory overflow. #define  TYPE_CYCLE68   unsigned int   Used by cycle counters. Typedefs typedef void(  linefunc68_t )(int, int)   First level (16 lines) decoder function. typedef _io68_t  io68_t   IO emulator plugin structure. typedef unsigned int  cycle68_t   At least 32 bit integer. Define Documentation #define IO68_NO_INT   (0x80000000)   IO no pending interruption return value. The next_int function of IO plugin must return IO68_NO_INT when no interruption are expected. Typedef Documentation typedef struct _io68_t io68_t   IO emulator plugin structure. All 68K IO must have a filled io68_t structure to be warm plug or unplug with ioplug interface.
