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\&.
