# xcb\_list\_fonts\_names\_iterator(3)

get matching font names

Part of [xcb\_list\_fonts(3)](/xcb_list_fonts/3.md).

## NAME

xcb\_list\_fonts - get matching font names

## SYNOPSIS

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

### Request function

xcb\_list\_fonts\_cookie\_t **xcb\_list\_fonts**(xcb\_connection\_t \**conn*, uint16\_t *max\_names*, uint16\_t *pattern\_len*, const char \**pattern*);

### Reply datastructure

```

typedef struct xcb_list_fonts_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t names_len;
    uint8_t  pad1[22];
} xcb_list_fonts_reply_t;
```

### Reply function

xcb\_list\_fonts\_reply\_t \***xcb\_list\_fonts\_reply**(xcb\_connection\_t \**conn*, xcb\_list\_fonts\_cookie\_t *cookie*, xcb\_generic\_error\_t \*\**e*);

### Reply accessors

int **xcb\_list\_fonts\_names\_length**(const xcb\_list\_fonts\_reply\_t \**reply*);

xcb\_str\_iterator\_t **xcb\_list\_fonts\_names\_iterator**(const xcb\_list\_fonts\_reply\_t \**reply*);\

## REQUEST ARGUMENTS

- *conn*

  The XCB connection to X11.

- *max\_names*

  The maximum number of fonts to be returned.

- *pattern\_len*

  The length (in bytes) of *pattern*.

- *pattern*

  A font pattern, for example "-misc-fixed-\*".

  The asterisk (\*) is a wildcard for any number of characters. The question mark (?) is a wildcard for a single character. Use of uppercase or lowercase does not matter.

## REPLY FIELDS

- *response\_type*

  The type of this reply, in this case *XCB\_LIST\_FONTS*. 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).

- *names\_len*

  The number of font names.

## DESCRIPTION

Gets a list of available font names which match the given *pattern*.

## RETURN VALUE

Returns an *xcb\_list\_fonts\_cookie\_t*. Errors have to be handled when calling the reply function *xcb\_list\_fonts\_reply*.

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

## ERRORS

This request does never generate any errors.
