c++ - Add, enable, disable log4cxx ConsoleAppender at runtime -

-

how dynamically turn log4cxx logging console on , off in application?

goal here process used choice, command line parm or gui input or whatever. in hypothetical main loop:

if ( userwantstostartconsolelogger )     consolelogger( true ); if ( userwantstostopconsolelogger )     consolelogger( false );

my logging setup is:

#include <log4cxx/logger.h> #include <log4cxx/propertyconfigurator.h> #include <log4cxx/helpers/exception.h>  int main( int argc, char** argv ) {    const log4cxx::loggerptr   logger;    log4cxx::propertyconfigurator::configure("./logs.config"); }

where ./logs.config looks like:

log4j.rootlogger=info, file  log4j.appender.stdout=org.apache.log4j.consoleappender log4j.appender.stdout.layout=org.apache.log4j.patternlayout log4j.appender.stdout.layout.conversionpattern=%5p [%t] (%f:%l) - %m%n  log4j.appender.file=org.apache.log4j.rollingfileappender log4j.appender.file.file=logs/system.logs log4j.appender.file.maxfilesize=1mb log4j.appender.file.maxbackupindex=10 log4j.appender.file.layout=org.apache.log4j.patternlayout log4j.appender.file.layout.conversionpattern=%d{mm/dd/yyyy hh:mm:ss:sss a}  %p  %c  %m%n

note: presently, have add , stdout after file in rootlogger= line accomplish this.

in context, of course, question is, goes in consolelogger() function?
