Function pamoja_envelope_body 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_envelope_body(
    bytes: *const u8,
    len: usize,
) -> *mut PamojaBuffer

Copies out the signed body of an envelope, without checking the signature.

This is what a gateway relays onward unchanged, and what a device hashes when it checks the signature itself.

Arguments

• bytes - the signed envelope.
• len - the length of bytes.

Returns

A buffer the caller must release with pamoja_buffer_free, or null if the envelope is malformed.

Safety

bytes must point to at least len readable bytes, or be null when len is 0.
