GLib.UriParamsIter.next

### Method

# GLib UriParamsIternext

since: 2.66

#### Declaration [src]

    gboolean
    g_uri_params_iter_next (
      GUriParamsIter* iter,
      gchar** attribute,
      gchar** value,
      GError** error
    )

#### Description [src]

Advances `iter` and retrieves the next attribute/value. `FALSE` is returned if an error has occurred (in which case `error` is set), or if the end of the iteration is reached (in which case `attribute` and `value` are set to `NULL` and the iterator becomes invalid). If `TRUE` is returned, `g_uri_params_iter_next()` may be called again to receive another attribute/value pair.

Note that the same `attribute` may be returned multiple times, since URIs allow repeated attributes.

Available since: 2.66

#### Parameters

`attribute`

  Type: `gchar**`

  On return, contains the attribute, or `NULL`.

  The argument will be set by the function.
  The argument can be set to `NULL` by the method.
  The argument can be `NULL`.
  The caller of the method takes ownership of the returned data, and is responsible for freeing it.
  The value is a NUL terminated UTF-8 string.

`value`

  Type: `gchar**`

  On return, contains the value, or `NULL`.

  The argument will be set by the function.
  The argument can be set to `NULL` by the method.
  The argument can be `NULL`.
  The caller of the method takes ownership of the returned data, and is responsible for freeing it.
  The value is a NUL terminated UTF-8 string.

`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 method 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: `gboolean`

`FALSE` if the end of the parameters has been reached or an error was encountered. `TRUE` otherwise.
