Function Documentation

gboolean purple_log_common_deleter (  PurpleLog *  log  )

Deletes a log. This function should only be used with logs that are written with purple_log_common_writer(). It's intended to be used as a "common" implementation of a logger's delete function. It should only be passed to purple_log_logger_new() and never called directly. Parameters: log  The PurpleLog to delete. Returns: A boolean indicating success or failure.

gboolean purple_log_common_is_deletable (  PurpleLog *  log  )

Checks to see if a log is deletable. This function should only be used with logs that are written with purple_log_common_writer(). It's intended to be used as a "common" implementation of a logger's is_deletable function. It should only be passed to purple_log_logger_new() and never called directly. Parameters: log  The PurpleLog to check. Returns: A boolean indicating if the log is deletable.

GList* purple_log_common_lister (  PurpleLogType  type, const char *  name, PurpleAccount *  account, const char *  ext, PurpleLogLogger *  logger )

Returns a sorted GList of PurpleLogs of the requested type. This function should only be used with logs that are written with purple_log_common_writer(). It's intended to be used as a "common" implementation of a logger's list function. It should only be passed to purple_log_logger_new() and never called directly. Parameters: type  The type of the logs being listed. name  The name of the log. account  The account of the log. ext  The file extension this log format uses. logger  A reference to the logger struct for this log. Returns: A sorted GList of PurpleLogs matching the parameters.

int purple_log_common_sizer (  PurpleLog *  log  )

Returns the size of a given PurpleLog. This function should only be used with logs that are written with purple_log_common_writer(). It's intended to be used as a "common" implementation of a logger's size function. It should only be passed to purple_log_logger_new() and never called directly. Parameters: log  The PurpleLog to size. Returns: An integer indicating the size of the log in bytes.

int purple_log_common_total_sizer (  PurpleLogType  type, const char *  name, PurpleAccount *  account, const char *  ext )

Returns the total size of all the logs for a given user, with a given extension. This function should only be used with logs that are written with purple_log_common_writer(). It's intended to be used as a "common" implementation of a logger's total_size function. It should only be passed to purple_log_logger_new() and never called directly. Parameters: type  The type of the logs being sized. name  The name of the logs to size (e.g. the username or chat name). account  The account of the log. ext  The file extension this log format uses. Returns: The size of all the logs with the specified extension for the specified user.

void purple_log_common_writer (  PurpleLog *  log, const char *  ext )

Opens a new log file in the standard Purple log location with the given file extension, named for the current time, for writing. If a log file is already open, the existing file handle is retained. The log's logger_data value is set to a PurpleLogCommonLoggerData struct containing the log file handle and log path. This function is intended to be used as a "common" implementation of a logger's write function. It should only be passed to purple_log_logger_new() and never called directly. Parameters: log  The log to write to. ext  The file extension to give to this log file.

gint purple_log_compare (  gconstpointer  y, gconstpointer  z )

Implements GCompareFunc for PurpleLogs. Parameters: y  A PurpleLog z  Another PurpleLog Returns: A value as specified by GCompareFunc

gboolean purple_log_delete (  PurpleLog *  log  )

Deletes a log. Parameters: log  The log Returns: A boolean indicating success or failure

void purple_log_free (  PurpleLog *  log  )

Frees a log. Parameters: log  The log to destroy

void* purple_log_get_handle (  void   )

Returns the log subsystem handle. Returns: The log subsystem handle.

char* purple_log_get_log_dir (  PurpleLogType  type, const char *  name, PurpleAccount *  account )

Returns the default logger directory Purple uses for a given account and username. This would be where Purple stores logs created by the built-in text or HTML loggers. Parameters: type  The type of the log. name  The name of the log. account  The account. Returns: The default logger directory for Purple.

GHashTable* purple_log_get_log_sets (  void   )

Returns a GHashTable of PurpleLogSets. A "log set" here means the information necessary to gather the PurpleLogs for a given buddy/chat. This information would be passed to purple_log_list to get a list of PurpleLogs. The primary use of this function is to get a list of everyone the user has ever talked to (assuming he or she uses logging). The GHashTable that's returned will free all log sets in it when destroyed. If a PurpleLogSet is removed from the GHashTable, it must be freed with purple_log_set_free(). Returns: A GHashTable of all available unique PurpleLogSets

GList* purple_log_get_logs (  PurpleLogType  type, const char *  name, PurpleAccount *  account )

Returns a list of all available logs. Parameters: type  The type of the log name  The name of the log account  The account Returns: A sorted list of PurpleLogs

int purple_log_get_size (  PurpleLog *  log  )

Returns the size of a log. Parameters: log  The log Returns: The size of the log, in bytes

GList* purple_log_get_system_logs (  PurpleAccount *  account  )

Returns a list of all available system logs. Parameters: account  The account Returns: A sorted list of PurpleLogs

int purple_log_get_total_size (  PurpleLogType  type, const char *  name, PurpleAccount *  account )

Returns the size, in bytes, of all available logs in this conversation. Parameters: type  The type of the log name  The name of the log account  The account Returns: The size in bytes

gboolean purple_log_is_deletable (  PurpleLog *  log  )

Tests whether a log is deletable. A return value of FALSE indicates that purple_log_delete() will fail on this log, unless something changes between the two calls. A return value of TRUE, however, does not guarantee the log can be deleted. Parameters: log  The log Returns: A boolean indicating if the log is deletable

void purple_log_logger_add (  PurpleLogLogger *  logger  )

Adds a new logger. Parameters: logger  The new logger to add

void purple_log_logger_free (  PurpleLogLogger *  logger  )

Frees a logger. Parameters: logger  The logger to free

The following functions are currently available (in order): create, write, finalize, list, read, size, total_size, list_syslog, get_log_sets, remove, is_deletable. For details on these functions, see PurpleLogLogger. Functions may not be skipped. For example, passing create and write is acceptable (for a total of two functions).

Creates a new log. Parameters: type  The type of log this is. name  The name of this conversation (screenname, chat name, etc.) account  The account the conversation is occurring on conv  The conversation being logged time  The time this conversation started tm  The time this conversation started, with timezone data, if available and if struct tm has the BSD timezone fields.
