Querying OpenCL™ Platform ID
OpenCL™ Runtime and Compiler for Intel® Processor Graphics
The following example shows how to query the OpenCL platforms to get the platform ID:
cl_platform_id * platforms = NULL;
char vendor_name[128] = {0};
cl_uint num_platforms = 0;
// get number of available platforms
cl_int err = clGetPlatformIDs(0, NULL, & num_platforms);
if (CL_SUCCESS != err)
{
// handle error
}
platforms = (cl_platform_id*)malloc(
sizeof(cl_platform)* num_platforms);
if (NULL == platforms)
{
// handle error
}
err = clGetPlatformIDs(num_platforms, platforms, NULL);
if (CL_SUCCESS != err)
{
// handle error
}
for (cl_uint ui=0; ui< num_platforms; ++ui)
{
err = clGetPlatformInfo(platforms[ui],
CL_PLATFORM_VENDOR,
128 * sizeof(char),
vendor_name,
NULL);
if (CL_SUCCESS != err)
{
// handle error
}
if (vendor_name != NULL)
{
if (!strcmp(vendor_name, "Intel(R) Corporation"))
{
return platforms[ui];
}
}
}
// handle error
