Function pamoja_lorawan_header_parse 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_lorawan_header_parse(
    bytes: *const u8,
    bytes_len: usize,
    out_header: *mut PamojaLorawanHeader,
) -> PamojaStatus

Reads a frame far enough to route it, without any key.

A receiver holding many sessions uses this to find which one a frame belongs to: the device address travels in the clear, so it can be read before the session that would verify the frame is even known.

Arguments

• bytes - the raw frame as it came off the radio.
• bytes_len - its length.
• out_header - receives the header fields.

Returns

PamojaStatus::Ok on success, with *out_header filled in, or PamojaStatus::Codec if the frame is truncated, carries a message type this build does not read, or declares more frame options than it holds.

Safety

bytes must point to at least bytes_len readable bytes when that length is non-zero, and out_header must point to a writable PamojaLorawanHeader.
