NAME

rtcSetDeviceErrorFunction - sets an error callback function for the device

SYNOPSIS

#include <embree3/rtcore.h>

typedef void (*RTCErrorFunction)(
  void* userPtr,
  RTCError code,
  const char* str
);

void rtcSetDeviceErrorFunction(
  RTCDevice device,
  RTCErrorFunction error,
  void* userPtr
);

DESCRIPTION

Using the rtcSetDeviceErrorFunction call, it is possible to set a callback function (error argument) with payload (userPtr argument), which is called whenever an error occurs for the specified device (device argument).

Only a single callback function can be registered per device, and further invocations overwrite the previously set callback function. Passing NULL as function pointer disables the registered callback function.

When the registered callback function is invoked, it gets passed the user-defined payload (userPtr argument as specified at registration time), the error code (code argument) of the occurred error, as well as a string (str argument) that further describes the error.

The error code is also set if an error callback function is registered.

EXIT STATUS

On failure an error code is set that can be queried using rtcGetDeviceError.
