Function soapysdr_sys::SoapySDRDevice_lastError

pub unsafe extern "C" fn SoapySDRDevice_lastError() -> *const c_char

Get the last error message after a device call fails. When an device API call throws, the C bindings catch the exception, store its message in thread-safe storage, and return a non-zero status code to indicate failure. Use lastError() to access the exception’s error message.
