Provides plugin access to communication channel

Fields

read_packet: Option<unsafe extern "C" fn(vio: *mut st_plugin_vio, buf: *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 "C" fn(vio: *mut st_plugin_vio, packet: *const c_uchar, packet_len: 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 "C" fn(vio: *mut st_plugin_vio, info: *mut st_plugin_vio_info)>

Fills in a st_plugin_vio_info structure, providing the information about the connection.
