rtcGetDeviceLastErrorMessage(3)

  NAME

    rtcGetDeviceLastErrorMessage - returns a message corresponding
      to the last error code

  SYNOPSIS

    #include <embree4/rtcore.h>

    const char* rtcGetDeviceLastErrorMessage(RTCDevice device);

  DESCRIPTION

This function can be used to get a message corresponding to the last error code (returned by rtcGetDeviceError) which often provides details about the error that happened. The message is the same as the message that will written to console when verbosity is > 0 or which is passed as the str argument of the RTCErrorFunction (see [rtcSetDeviceErrorFunction]). However, when device construction fails this is the only way to get additional information about the error. In this case, rtcNewDevice returns NULL as device. To query the error message for such a failed device construction, pass NULL as device to the rtcGetDeviceLastErrorMessage function. For all other invocations of rtcGetDeviceLastErrorMessage, a proper device pointer must be specified.

  EXIT STATUS

Returns a message corresponding to the last error code.
