You can register your own appender through log4cxx.  For example (cribbed
from roscpp/src/libros/file_log.cpp:

    const log4cxx::LoggerPtr& logger =
log4cxx::Logger::getLogger(ROSCONSOLE_DEFAULT_NAME ".<your_name>");
    log4cxx::LayoutPtr layout = new log4cxx::PatternLayout("[%c] [%d]
[thread %t]: [%p] %m\n");
    log4cxx::RollingFileAppenderPtr appender = new
log4cxx::RollingFileAppender(layout, <your logfile name>, false);
    appender->setMaximumFileSize(100*1024*1024);
    appender->setMaxBackupIndex(10);
    log4cxx::helpers::Pool pool;
    appender->activateOptions(pool);
    logger->addAppender(appender);
