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