The API:
======================================================================
1) client side:
---------------
lcp_client_t *lcp_open (const char *name);
int lcp_close (lcp_client_t *client);
int lcp_write (lcp_client_t *client,
unsigned long plugin,
unsigned long port,
LADSPA_Data value);
int lcp_read (lcp_client_t *client,
unsigned long plugin,
unsigned long port,
LADSPA_Data *value);
2) server side:
---------------
typedef void (*lcp_server_write_callback_t)(void *,
unsigned long,
unsigned long,
LADSPA_Data value);
typedef void (*lcp_server_read_callback_t)(void *,
unsigned long,
unsigned long,
LADSPA_Data *value);
lcp_server_t *lcp_server_start (const char *name,
lcp_server_write_callback_t,
void *write_arg,
lcp_server_read_callback_t,
void *read_arg);
void lcp_server_stop (lcp_server_t *);
int lcp_server_handle_message (lcp_server_t *server, int fd);
int lcp_server_accept (int fd);
======================================================================
The tarball contains two tiny GTK programs:
s: a sample server
c: a sample client
that demonstrate the interfacing of the server and client side API
into a typical GUI (i.e. adding file descriptors to a "watch list"
managed by the GUI toolkits' main event loop).
There are no dependencies in the library itself upon any external
libraries (other than glibc, obviously).
Comments welcome. I will be merging this into Ardour after an initial
round of feedback.
