static const char * | debugFile () |
Reads the environment variable QGIS_DEBUG_FILE. |
The advantage of this class over iostream & co. is that the output can be controlled with environment variables: QGIS_DEBUG is an int describing what debug messages are written to the console. If the debug level of a message is <= QGIS_DEBUG, the message is written to the console. It the variable QGIS_DEBUG is not defined, it defaults to 1 for debug mode and to 0 for release mode QGIS_DEBUG_FILE may contain a file name. Only the messages from this file are printed (provided they have the right debuglevel). If QGIS_DEBUG_FILE is not set, messages from all files are printed
