Gcr.Prompt.password_run

### Method

# Gcr Promptpassword_run

#### Declaration [src]

    const gchar*
    gcr_prompt_password_run (
      GcrPrompt* prompt,
      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Prompts for password. Set the various properties on the prompt before calling this method to explain which password should be entered.

This method will block until the a response is returned from the prompter and will run a main loop similar to a gtk_dialog_run(). The application will remain responsive but care must be taken to handle reentrancy issues.

A password will be returned if the user enters a password successfully. The returned password is valid until the next time a method is called to display another prompt.

`NULL` will be returned if the user cancels or if an error occurs. Check the `error` argument to tell the difference.

#### Parameters

`cancellable`

  Type: `GCancellable`

  Optional cancellation object.

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

`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: `const gchar*`

The password owned by the prompt, or `NULL`.

The returned data is owned by the instance.
The value is a NUL terminated UTF-8 string.
