Provides plugin access to communication channel
Fields
read_packet: Option<unsafe extern fn(_: *mut st_plugin_vio, _: *mut *mut c_uchar) -> c_int>
Plugin provides a pointer reference and this function sets it to the contents of any incoming packet. Returns the packet length, or -1 if the plugin should terminate.
write_packet: Option<unsafe extern fn(_: *mut st_plugin_vio, _: *const c_uchar, _: c_int) -> c_int>
Plugin provides a buffer with data and the length and this function sends it as a packet. Returns 0 on success, 1 on failure.
info: Option<unsafe extern fn(_: *mut st_plugin_vio, _: *mut st_plugin_vio_info)>
Fills in a st_plugin_vio_info structure, providing the information about the connection.
