# xcb\_glx\_make\_context\_current(3)

## NAME

xcb\_glx\_make\_context\_current -

## SYNOPSIS

**#include \<xcb/glx.h\>**

### Request function

xcb\_glx\_make\_context\_current\_cookie\_t **xcb\_glx\_make\_context\_current**(xcb\_connection\_t \**conn*, xcb\_glx\_context\_tag\_t *old\_context\_tag*, xcb\_glx\_drawable\_t *drawable*, xcb\_glx\_drawable\_t *read\_drawable*, xcb\_glx\_context\_t *context*);

### Reply datastructure

```

typedef struct xcb_glx_make_context_current_reply_t {
    uint8_t               response_type;
    uint8_t               pad0;
    uint16_t              sequence;
    uint32_t              length;
    xcb_glx_context_tag_t context_tag;
    uint8_t               pad1[20];
} xcb_glx_make_context_current_reply_t;
```

### Reply function

xcb\_glx\_make\_context\_current\_reply\_t \***xcb\_glx\_make\_context\_current\_reply**(xcb\_connection\_t \**conn*, xcb\_glx\_make\_context\_current\_cookie\_t *cookie*, xcb\_generic\_error\_t \*\**e*);\

## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *old\_context\_tag*

  TODO: NOT YET DOCUMENTED.

- *drawable*

  TODO: NOT YET DOCUMENTED.

- *read\_drawable*

  TODO: NOT YET DOCUMENTED.

- *context*

  TODO: NOT YET DOCUMENTED.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_GLX\_MAKE\_CONTEXT\_CURRENT*. This field is also present in the *xcb\_generic\_reply\_t* and can be used to tell replies apart from each other.

- *sequence*

  The sequence number of the last request processed by the X11 server.

- *length*

  The length of the reply, in words (a word is 4 bytes).

- *context\_tag*

  TODO: NOT YET DOCUMENTED.

## DESCRIPTION

## RETURN VALUE

Returns an *xcb\_glx\_make\_context\_current\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_glx\_make\_context\_current\_reply*.

If you want to handle errors in the event loop instead, use *xcb\_glx\_make\_context\_current\_unchecked*. See **[xcb-requests(3)](/xcb-requests/3.md)** for details.

## ERRORS

This request does never generate any errors.
