Header file: "DL_LogFile_handler.h"
This header provides utility functions to use the logger daemon to handle logger files.
7.3.6.4.1 ylogd_request_data_logger_file
Function Description
sint32 ylogd_request_data_logger_file (const T_DBUS_Util *const opt_DBusInstance, const
charn * const opcn_DataLoggerName, charn * const opcn_DataLoggerPath, const uint16
ou16_BufferSize)
The function requests the datalogger file opcn_DataLoggerName. If the logger file exists, the path to a copy
(tmp file) will be responded via the variable opcn_DataLoggerPath. The maximal length of the path to the
datalogger copy is defined via ou16_BufferSize.
