       __LOG4C_BEGIN_DECLS const log4c_appender_type_t log4c_appender_type_mmap

Detailed Description

       Log4c mmap(2) appender interface.

       The mmap appender uses a fixed length memory mapped file for logging. The appender's name
       is used as the file name which will be opened and mapped to memory at first use. The
       memory mapped file is then used as a rotating buffer in which logging events are written.

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

       log4c_appender_t* myappender;

       myappender = log4c_appender_get("myfile.log");
       log4c_appender_set_type(myappender, &log4c_appender_type_mmap);

           the file is not created at first use. It should already exist and have a reasonable
           size, a mutilple of a page size.

   __LOG4C_BEGIN_DECLS const log4c_appender_type_t log4c_appender_type_mmap
       Mmap appender type definition.

       This should be used as a parameter to the log4c_appender_set_type() routine to set the
       type of the appender.
