## Detailed Description

This header is included by all files that need to use the DMX logging facilities.

## Enumeration Type Documentation

enum dmxLogLevel

| Logging levels -- output is tunable with dmxSetLogLevel.

Enumeration values:

  dmxDebug | Usually verbose debugging info

## Function Documentation

const char* dmxEventName | ( | int | type | ) |

| Translate an event type into a human-readable string.

dmxLogLevel dmxGetLogLevel | ( | void |  | ) |

| Returns the log level set by dmxLogLevel.

void dmxLog | ( | dmxLogLevel | logLevel,
|  | const char * | format,
|  | ... |
| ) |

| Log the specified message at the specified logLevel. format can be a printf-like format expression.

void dmxLogArgs | ( | dmxLogLevel | logLevel,
|  | int | argc,
|  | char ** | argv
| ) |

| Print argc messages, each describing an element in argv. This is maingly for debugging purposes.

void dmxLogCont | ( | dmxLogLevel | logLevel,
|  | const char * | format,
|  | ... |
| ) |

| Continue a log message without printing the message prefix.

void dmxLogInput | ( | DMXInputInfo * | dmxInput,
|  | const char * | format,
|  | ... |
| ) |

| Log an informational message (at level dmxInfo) related to input. The message prefix will contain information from dmxInput.

void dmxLogInputCont | ( | DMXInputInfo * | dmxInput,
|  | const char * | format,
|  | ... |
| ) |

| Continue a message related to input without printing the message prefix.

void dmxLogOutput | ( | DMXScreenInfo * | dmxScreen,
|  | const char * | format,
|  | ... |
| ) |

| Log an informational message (at level dmxInfo) related to ouput. The message prefix will contain backend information from dmxScreen.

void dmxLogOutputCont | ( | DMXScreenInfo * | dmxScreen,
|  | const char * | format,
|  | ... |
| ) |

| Continue a message related to output without printing the message prefix.

void dmxLogOutputWarning | ( | DMXScreenInfo * | dmxScreen,
|  | const char * | format,
|  | ... |
| ) |

| Log a warning message (at level dmxWarning) related to output. The message prefix will contain backend information from dmxScreen.

void dmxLogVisual | ( | DMXScreenInfo * | dmxScreen,
|  | XVisualInfo * | vi,
|  | int | defaultVisual
| ) |

| Print messages at level dmxInfo describing the visuals in vi.

dmxLogLevel dmxSetLogLevel | ( | dmxLogLevel | newLevel | ) |
