GLib.Uri.is_valid
Description: Reference for GLib.Uri.is_valid

### Function

# GLib Uriis_valid

since: 2.66

#### Declaration

    gboolean
    g_uri_is_valid (
      const gchar* uri_string,
      GUriFlags flags,
      GError** error
    )

#### Description

Parses `uri_string` according to `flags`, to determine whether it is a valid absolute URI, i.e. it does not need to be resolved relative to another URI using g_uri_parse_relative().

If it’s not a valid URI, an error is returned explaining how it’s invalid.

See g_uri_split(), and the definition of `GUriFlags`, for more information on the effect of `flags`.

Available since: 2.66

#### Parameters

`uri_string`

  Type: `const gchar*`

  A string containing an 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 for parsing `uri_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 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: `gboolean`

`TRUE` if `uri_string` is a valid absolute URI, `FALSE` on error.
