This directory should contain the mice-protocol implementations.
Each file (or if bigger: directory) implements one protocol.
You have to create three functions:
gpm2_open_<protocol>();
gpm2_handle_<protocol>();
gpm2_close_<protocol>();
It's not yet clear, how to register protocols to gpm2.
First idea of inclusion:
- create deps/mouse-<protocol> containging all dependencies
- conf/built-options/mice specifies which mice protocols to include
- a script generates include/gpm2-daemon-mice.h containg a struct-array
that looks like:
struct mice_protos {
char *name;
int (*open)();
int (*handle)();
int (*open)();
};
--------------------------------------------------------------------------------
More design ideas for using mice:
- The gpm2_handle function gets a pointer to a char array containing the
data packet.
- The gpm2_handle function returns what the packet means
- gpm2_daemon may then decide what todo with this information
--------------------------------------------------------------------------------
It would be nice to have a read_config_<proto> that reads and verifies
the protocol specific options.
For this, it would be nice to have a libcconfig() like this:
struct cconfig_fd *cconfig_open(char *dir);
struct cconfig_tree *cconfig_read_tree(struct cconfig_fd *which);
struct cconfig_element *cconfig_select_below(char *basepath, struct cconfig_fd *which, ...);
The tree, cconfig_read_tree creates could consist of elements
of the following definition:
struct cconfig_element {
char *path;
struct stat sbuf;
};
--------------------------------------------------------------------------------
gpm2_open_*:
- needs fd
- needs options
--------------------------------------------------------------------------------
struct datapacket *gpm2_read_*(int fd)
- reads one packet
- returns it
--------------------------------------------------------------------------------
