Function pamoja_lorawan_grant_session 

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

Derives the session a grant activates, the same one the device computes.

Arguments

• grant - the address and settings granted.
• 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_session - receives the session.

Returns

PamojaStatus::Ok on success, with *out_session set to a handle the caller must release with pamoja_lorawan_session_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_session must point to a writable *mut PamojaLorawanSession.
