| Imgtool | Imgtool is used to access files stored in native disk images. For example, you can manipulate Apple II disks and extract files, or rename a file on a VZ200 disk. Modules To add support for a new format, you have to write an imgtool module. Those modules implement various functions that are then called by imgtool to perform the specific task. Those functions are: | reference, mess, tools, imgtool |
| SYSTEM_CONFIG | The SYSTEM_CONFIG macro is used by MESS drivers to provide info about devices and the ram size. Syntax CONFIG_RAM and CONFIG_RAM_DEFAULT When the CONFIG_RAM and/or CONFIG_RAM_DEFAULT options are used in a driver then the MESS framework will make sure the following global variables are set and ready for use by the driver: | reference, mess, macro |
| cpunum_set_input_line() | Set the logical state of the an input line on a CPU. Syntax Declaration Declared in src/emu/cpuint.h as void cpunum_set_input_line(running_machine *machine, int cpunum, int line, int state); Parameters * machine -- Pointer to the machine where this CPU is running * cpunum -- Index to the CPU * line -- The IRQ to set, those are generally defined in the appropriate CPU header files * state -- The logical state to set. Possible values are ASSERT_LINE, HOLD_LINE, CLEAR_LINE and PULSE_… | reference, mame, cpu, irq |
| cpunum_set_input_line_and_vector() | Set the logical state of an input line on a CPU and its associated vector. This function is a combined version of cpunum_set_input_line() and cpunum_set_input_line_vector(). Syntax Declaration Declared in src/emu/cpuint.h as void cpunum_set_input_line_and_vector(running_machine *machine, int cpunum, int line, int state, int vector); | reference, mame, cpu, irq |
| cpunum_set_input_line_vector() | Set the vector to be returned during a CPU's interrupt acknowledge cycle. Syntax Declaration Declared in src/emu/cpuint.h as void cpunum_set_input_line_vector(int cpunum, int irqline, int vector); Parameters * cpunum -- Index to the CPU * irqline -- The IRQ to set, those are generally defined in the appropriate CPU header files * vector -- The vector you want to set | reference, mame, cpu, irq |
| cpunum_set_irq_callback() | Install a driver callback for IRQ acknowledge. This callback is used to get a vector for an IRQ line. Syntax Declaration Declared in src/emu/cpuint.h as void cpunum_set_irq_callback(int cpunum, int (*callback)(int irqline)); Parameters * cpunum -- Index to the CPU * *callback -- Pointer to a function that will be called when this IRQ is fired. | reference, mame, cpu, irq |
| device_getinfo | The device_getinfo functions are used by MESS to get additional info about the devices used in a system. They are generally located in the systems/<drivername>.c file. Syntax All data that you want to return must be copied into the info union. A switch is used to selected the info MESS wants. Possible states are: | reference, mess, devices |
| logerror() | The logerror() function is used to output text to the standard error.log file (if the log option is enabled) and is also visible in a debugger error output window. Syntax Declaration Declared in src/emu/mame.h as void CLIB_DECL logerror(const char *format, ...) ATTR_PRINTF(1,2); | reference, mame, debug, log |
| mame_rand() | The mame_rand() function returns a standardized random number. Syntax Declaration Declared in src/emu/mame.h as UINT32 mame_rand(running_machine *machine); Parameters * *machine -- Pointer to the currently running machine. Returns A random number. | reference, mame, other |
| popmessage() | The popmessage() function is used to display on-screen info at the bottom of the emulated display. Syntax Declaration Declared in src/emu/mame.h as void CLIB_DECL popmessage(const char *format, ...) ATTR_PRINTF(1,2); Parameters * *format -- Pointer to a const char with the text to be printed. Supports printf-style parameters. Can be NULL, in this case the displayed message is cleared immediately. * ... -- A list of variables that are referenced in the text. | reference, mame, debug, log |
| read_file() | The read_file() function is called when the user requests a file to be read from the source image. Syntax Declaration Declared in src/mess/tools/imgtool/library.h as Parameters * partition -- Pointer to an imgtool_partition where the file is. * filename -- Pointer to a string with the filename of the file the user wants to read. * fork -- Pointer to a string with a resource fork. Only used for Macintosh filesystems. * destf -- Pointer to an imgtool_stream to write the file data to. | reference, mess, imgtool, imgtoolinfo function |
| stream_write() | The stream_write() function is used to write to data to imgtool_streams. Syntax Declaration Declared in src/mess/tools/imgtool/stream.h as UINT32 stream_write(imgtool_stream *stream, const void *buf, UINT32 sz); Parameters * stream -- Pointer to the imgtool_stream where the data should be written. * buf -- Pointer to a buffer with the data. * sz -- Amount of bytes to write. | reference, mess, imgtool, stream |
