Struct libosdp_sys::osdp_channel

#[repr(C)]
pub struct osdp_channel {
    pub data: *mut c_void,
    pub id: c_int,
    pub recv: osdp_read_fn_t,
    pub send: osdp_write_fn_t,
    pub flush: osdp_flush_fn_t,
}

@brief User defined communication channel abstraction for OSDP devices. The methods for read/write/flush are expected to be non-blocking.

Fields

data: *mut c_void

pointer to a block of memory that will be passed to the send/receive/flush method. This is optional (can be set to NULL)

id: c_int

channel_id; On multi-drop networks, more than one PD can share the same channel (read/write/flush pointers). On such networks, the channel_id is used to lock a PD to a channel. On multi-drop networks, this id must non-zero and be unique for each bus.

recv: osdp_read_fn_t

Pointer to function used to receive osdp packet data

send: osdp_write_fn_t

Pointer to function used to send osdp packet data

flush: osdp_flush_fn_t

Pointer to function used to flush the channel (optional)
