Function pamoja_lorawan_grant_accept 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_lorawan_grant_accept(
    grant: PamojaLorawanGrant,
    cflist: *const u8,
    cflist_len: usize,
    app_key: *const u8,
    app_key_len: usize,
    dev_nonce: u16,
    out_frame: *mut *mut PamojaBuffer,
) -> PamojaStatus

Builds the signed join-accept a network sends to admit a device.

Arguments

• grant - the address and settings to grant.
• cflist - the optional 16-byte channel list, or null for none.
• cflist_len - its length, either 0 or 16.
• app_key - the 16-byte application root key the device shares.
• app_key_len - its length, which must be PAMOJA_LORAWAN_KEY_LEN.
• dev_nonce - the nonce the matching join-request carried.
• out_frame - receives the encoded join-accept.

Returns

PamojaStatus::Ok on success, with *out_frame set to a buffer the caller must release with pamoja_buffer_free, or PamojaStatus::InvalidArgument if the key or the channel list is the wrong length.

Safety

cflist and app_key must each point to at least their stated lengths in readable bytes, and out_frame must point to a writable *mut PamojaBuffer.
