我在此行中收到了访问冲突异常
err = clGetPlatformIDs(0, NULL, &numPlatforms);
我可以做些什么来防止此异常。 我使用的是AMD App SDK 3.0。我的PC配置是核心i7 5500U CPU和AMD R5 M230 GPU，Windows 10 64位。
我的完整计划就在这里。
#include<stdio.h>
#include<CL/cl.h>
int main(void){
cl_int err;
cl_uint numPlatforms;
err = clGetPlatformIDs(0, NULL, &numPlatforms);
if (CL_SUCCESS == err)
printf("\nDetected OpenCL platforms: %d", numPlatforms);
else
printf("\nError calling clGetPlatformIDs. Error code: %d", err);
return 0;
}
