GLib.Uri.resolve_relative
Description: Reference for GLib.Uri.resolve_relative

### Function

# GLib Uriresolve_relative

since: 2.66

#### Declaration

    gchar*
    g_uri_resolve_relative (
      const gchar* base_uri_string,
      const gchar* uri_ref,
      GUriFlags flags,
      GError** error
    )

#### Description

Parses `uri_ref` according to `flags` and, if it is a relative URI, resolves it relative to `base_uri_string`. If the result is not a valid absolute URI, it will be discarded, and an error returned.

(If `base_uri_string` is `NULL`, this just returns `uri_ref`, or `NULL` if `uri_ref` is invalid or not absolute.)

Available since: 2.66

#### Parameters

`base_uri_string`

  Type: `const gchar*`

  A string representing a base URI.

  The argument can be `NULL`.
  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`uri_ref`

  Type: `const gchar*`

  A string representing a relative or absolute URI.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`flags`

  Type: `GUriFlags`

  Flags describing how to parse `uri_ref`.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `gchar*`

The resolved URI string, or NULL on error.

The caller of the function takes ownership of the data, and is responsible for freeing it.
The value is a NUL terminated UTF-8 string.
