SYNOPSIS

Detailed Description

Log4c stream appender interface.

The stream appender uses a file handle FILE* for logging. The appender's name is used as the file name which will be opened at first log. An appender can also be associated to an opened file handle using the log4c_appender_set_udata() method to update the appender user data field. In this last case, the appender name has no meaning. 2 default stream appenders are defined: 'stdout' and 'stderr'.

The following examples shows how to define and use stream appenders.

the simple way

 log4c_appender_t* myappender;
 myappender = log4c_appender_get('myfile.log');
 log4c_appender_set_type(myappender, &log4c_appender_type_stream);

the sophisticated way

 log4c_appender_t* myappender;
 myappender = log4c_appender_get('myappender');
    
 log4c_appender_set_type(myappender, &log4c_appender_type_stream);
 log4c_appender_set_udata(myappender, fopen('myfile.log', 'w'));
