# [NAME](#NAME)

xcb\_list\_fonts - get matching font names

# [SYNOPSIS](#SYNOPSIS)

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

## [Request function](#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](#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](#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](#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](#REQUEST_ARGUMENTS)

[*conn*](#conn)

The XCB connection to X11.

[*max\_names*](#max_names)

The maximum number of fonts to be returned.

[*pattern\_len*](#pattern_len)

The length (in bytes) of *pattern*.

[*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](#REPLY_FIELDS)

[*response\_type*](#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*](#sequence)

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

[*length*](#length)

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

[*names\_len*](#names_len)

The number of font names.

# [DESCRIPTION](#DESCRIPTION)

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

# [RETURN VALUE](#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)**](/man/os/libxcb/xcb-requests.3) for details.

# [ERRORS](#ERRORS)

This request does never generate any errors.
