# PAPI\_enum\_dev\_type(3)

returns handle of next device type

## NAME

PAPI\_enum\_dev\_type - returns handle of next device type

## SYNOPSIS

## Detailed Description

**Return values**

*ENOCMP* component does not exist \
 *EINVAL* end of device type list

**Parameters**

*enum\_modifier* device type modifier, used to filter out enumerated device types

**Example:**

```
enum {
    PAPI_DEV_TYPE_ENUM__FIRST,
    PAPI_DEV_TYPE_ENUM__CPU,
    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.
