    PAPI_DEV_TYPE_ENUM__CUDA,
    PAPI_DEV_TYPE_ENUM__ROCM,
    PAPI_DEV_TYPE_ENUM__ALL
};

void *handle;
const char *vendor_name;
int enum_modifier = PAPI_DEV_TYPE_ENUM__CPU | PAPI_DEV_TYPE_ENUM__CUDA;
while (PAPI_OK == PAPI_enum_dev_type(enum_modifier, &handle)) {
    PAPI_get_dev_type_attr(handle, PAPI_DEV_TYPE_ATTR__CHAR_NAME, &vendor_name);
    ...

PAPI_enum_dev_type() allows the user to access all device types in the system. It takes an enumerator modifier that allows users to enumerate only devices of a predefined type and it returns an opaque handler that users can pass to other functions in order to query device type attributes.
