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
.
