Description: Reference for Gio.AppInfo.launch_default_for_uri

### Function

# Gio AppInfolaunch_default_for_uri

#### Declaration [src]

    gboolean
    g_app_info_launch_default_for_uri (
      const char* uri,
      GAppLaunchContext* context,
      GError** error
    )

#### Description [src]

Utility function that launches the default application registered to handle the specified uri. Synchronous I/O is done on the uri to detect the type of the file if required.

The D-Bus–activated applications don’t have to be started if your application terminates too soon after this function. To prevent this, use `g_app_info_launch_default_for_uri_async()` instead.

#### Parameters

`uri`

  Type: `const char*`

  The uri to show.

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

`context`

  Type: `GAppLaunchContext`

  Optional launch context.

  The argument can be `NULL`.
  The data is owned by the caller of the function.

`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` on success, `FALSE` on error.
