## NAME

io\_uring\_opcode\_supported - is op code supported?

## SYNOPSIS

```
#include <liburing.h>
```

**int io\_uring\_opcode\_supported(struct io\_uring\_probe \****probe***,**                               **int** *opcode***);**

## DESCRIPTION

The function [**io\_uring\_opcode\_supported**(3)](/io_uring_opcode_supported/3.md) allows the caller to determine if the passed in *opcode* belonging to the *probe* param is supported. An instance of the io\_uring\_probe instance can be obtained by calling the function [**io\_uring\_get\_probe**(3)](/io_uring_get_probe/3.md).

## RETURN VALUE

On success it returns 1, otherwise it returns 0.
