Function pamoja_mavlink_crc16_mcrf4xx 

Source 
#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_mavlink_crc16_mcrf4xx(
    bytes: *const u8,
    bytes_len: usize,
) -> u16
Expand description

Returns the CRC-16/MCRF4XX checksum of a byte string.

This is the checksum every MAVLink frame carries, exposed because a host that implements part of the protocol itself still needs the same arithmetic.

§Arguments

  • bytes - the data to checksum.
  • bytes_len - how many bytes bytes holds.

§Returns

The checksum, or 0 if bytes is null with a non-zero length.

§Safety

When bytes_len is non-zero, bytes must point to at least bytes_len readable bytes.
