Service Example
This section discusses a very simple
Service
function called
simple_service.
All
this function does is send a message in response to a client request. The message is
initialized by the
init_simple_service
function during server initialization.
For a more complex example, see the file
service.c
in the
examples
directory,
which is discussed in “More Complex Service Example,” on page 231.
