Function pamoja_mavlink_signer_sign 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_mavlink_signer_sign(
    signer: *mut PamojaMavlinkSigner,
    header: PamojaMavlinkHeader,
    msgid: u32,
    payload: *const u8,
    payload_len: usize,
    crc_extra: u8,
    out_frame: *mut *mut PamojaMavlinkFrame,
) -> PamojaStatus

Signs a message into a v2 frame.

Each call advances the signer’s timestamp, which is what makes a replayed frame detectable.

Arguments

• signer - the signer to use.
• header - the addressing fields to stamp on the frame.
• msgid - the message id.
• payload - the message payload.
• payload_len - how many bytes payload holds.
• crc_extra - the seed for this message id.
• out_frame - set to the signed frame on success, and to null otherwise.

Returns

PamojaStatus::Ok on success.

Errors

Returns PamojaStatus::InvalidArgument if signer or out_frame is null, or the payload does not fit a frame.

Safety

signer must be a live signer handle, payload must point to payload_len readable bytes when the length is non-zero, and out_frame must point at writable storage for one pointer.
