### Struct

# GLibError

#### Description [src]

    struct GError {
      GQuark domain;
      gint code;
      gchar* message;
    }

The `GError` structure contains information about an error that has occurred.

###### Structure members

`domain`

  Error domain, e.g. `G_FILE_ERROR`.

`code`

  Error code, e.g. `G_FILE_ERROR_NOENT`.

`message`

  Human-readable informative error message.

#### Constructors

###### g_error_new

Creates a new `GError` with the given `domain` and `code`, and a message formatted with `format`.

###### g_error_new_literal

Creates a new `GError`; unlike g_error_new(), `message` is not a printf()-style format string. Use this function if `message` contains text you don’t have control over, that could include `printf()` escape sequences.

###### g_error_new_valist

Creates a new `GError` with the given `domain` and `code`, and a message formatted with `format`.

since: 2.22

#### Functions

###### g_error_domain_register

This function registers an extended `GError` domain. `error_type_name` will be duplicated. Otherwise does the same as g_error_domain_register_static().

since: 2.68

###### g_error_domain_register_static

This function registers an extended `GError` domain.

since: 2.68

#### Instance methods

###### g_error_copy

Makes a copy of `error`.

###### g_error_free

Frees a `GError` and associated resources.

###### g_error_matches

Returns `TRUE` if `error` matches `domain` and `code`, `FALSE` otherwise. In particular, when `error` is `NULL`, `FALSE` will be returned.
