## Detailed Description

Defines a logging infrastructure for the vmtools library based on glib's logging facilities. Wrap the commonly used logging functions (Log/Warning/Debug), and provides configurability for where logs should go to.

To choose the logging domain for your source file, define G_LOG_DOMAIN before including glib.h.

All fatal error messages will go to the 'syslog' handler no matter what handler has been configured.

## Macro Definition Documentation

## CLEAR_LOG_HANDLER

#define CLEAR_LOG_HANDLER | ( |  | handler | ) |

Value:
do { \
if ((handler) != NULL) { \
if (handler->logger != NULL) { \
handler->logger->dtor(handler->logger); \
} \
g_free((handler)->domain); \
g_free((handler)->type); \
g_free((handler)->confData); \
g_free(handler); \
} \
} while (0)

Clean up the contents of a log handler.

## DEFAULT_HANDLER

#define DEFAULT_HANDLER "file+"

The default handler to use if none is specified by the config data.

## DEFAULT_LOGFILE_NAME_PREFIX

#define DEFAULT_LOGFILE_NAME_PREFIX "/var/log/vmware"

The default logfile location.

## IS_FATAL

#define IS_FATAL | ( |  | level | ) | ((level) & G_LOG_FLAG_FATAL)

Tells whether the given log level is a fatal error.

## SAFE_HANDLER

#define SAFE_HANDLER "std"

The "failsafe" handler.

## SHOULD_LOG

#define SHOULD_LOG | ( |  | level,
|  |  | data
| ) |  |

Value:
(IS_FATAL(level) || \
(gLogEnabled && ((data)->mask & (level))))
IS_FATAL
#define IS_FATAL(level)
Definition: vmtoolsLog.c:92

Tells whether a message should be logged. All fatal messages are logged, regardless of what the configuration says. Otherwise, the log domain's configuration is respected.

## Typedef Documentation

## LogEntry

typedef struct LogEntry LogEntry

Structure for caching a log message

## Function Documentation

## Debug()

void Debug | ( | const char * | fmt,
|  |  | ...
| ) |  |

Logs a message using the G_LOG_LEVEL_DEBUG level.

Parameters

  [in] | fmt | Log message format.

## Log()

void Log | ( | const char * | fmt,
|  |  | ...
| ) |  |

Logs a message using the G_LOG_LEVEL_INFO level.

Parameters

  [in] | fmt | Log message format.

## LogV()

void LogV | ( | uint32 | routing,
|  | const char * | fmt,
|  | va_list | args
| ) |  |

Logs a message with the given log level.

Translates lib/log levels into glib levels, and sends the message to the log implementation.

Parameters

  [in] | level | Log level.
  [in] | fmt | Log message format.
  [in] | args | Log message arguments.

## Panic()

void Panic | ( | const char * | fmt,
|  |  | ...
| ) |  |

Logs a message using the G_LOG_LEVEL_ERROR level. In the default configuration, this will cause the application to terminate and, if enabled, to dump core.

Parameters

  [in] | fmt | Log message format.

## VMToolsAsprintf()

gint VMToolsAsprintf | ( | gchar ** | string,
|  | gchar const * | format,
|  |  | ...
| ) |  |

glib-based version of Str_Asprintf().

Parameters

  [out] | string | Where to store the result.
  [in] | format | String format.
  [in] | ... | String arguments.

Returns
  Number of bytes printed.

## Warning()

void Warning | ( | const char * | fmt,
|  |  | ...
| ) |  |

Logs a message using the G_LOG_LEVEL_WARNING level.

Parameters

  [in] | fmt | Log message format.
