#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_chirpstack_uplink_text(
    uplink: *const PamojaChirpstackUplink,
    field: u8,
) -> *mut PamojaString

Reads one of an uplink event’s text fields.

Arguments

• uplink - the event.
• field - one of the PAMOJA_CHIRPSTACK_* field constants.

Returns

The text, which the caller releases with pamoja_string_free; an empty string for a field the event left out; or null for a time the event left out, a null handle, or a field constant that names nothing.

Safety

uplink must be a live handle or null.
