## Detailed Description

Provides interface for reading DMX configuration files and for combining that information with command-line configuration parameters.

## Define Documentation

#define GEN | ( |  | param,
|  |  | glob,
|  |  | def |
| ) |  |  |

Value:

    void dmxConfigSet##glob(const char *param) {                                 \
         if (dmx##glob) free((void *)dmx##glob);                                  \
         dmx##glob = strdup(param);                                               \
     }                                                                            \
     char *dmxConfigGet##glob(void) {                                             \
         return (char *)(dmx##glob ? dmx##glob : def);                            \
     }

This macro is used to generate the following access methods:

- dmxConfig{Set,Get}rules
- dmxConfig{Set,Get}model
- dmxConfig{Set,Get}layout
- dmxConfig{Set,Get}variant
- dmxConfig{Set,Get}options These methods are used to read and write information about the keyboard.

## Typedef Documentation

typedef struct DMXConfigCmdStruct DMXConfigCmd

This stucture stores the parsed configuration information.

typedef struct DMXConfigCmdStruct * DMXConfigCmdPtr

typedef struct DMXConfigListStruct DMXConfigList

void dmxConfigSetMaxScreens | ( | void |  | ) |

This function determines the number of displays we WILL have and sets MAXSCREENS to that value. This is difficult since the number depends on the command line (which is easy to count) or on the config file, which has to be parsed.

void dmxConfigStoreConfig | ( | const char * | config | ) |

Make a note that config should be used as the configuration for current instantiation of the DMX server.

void dmxConfigStoreDisplay | ( | const char * | display | ) |

Make a note that display is the name of an X11 display that should be initialized as a backend (output) display. Called from ddxProcessArgument.
