* inf_user_status_from_string:
* @string: A string representation of a #InfUserStatus.
* @status: A pointer to a #InfUserStatus value, or %NULL.
* @error: Location to store error information, if any.
*
* This function does the opposite of inf_user_status_to_string(). It turns
* the given string back to a #InfUserStatus, storing the result in @status
* if @status is non-%NULL. If @string is invalid, then @status is left
* untouched, @error is set and %FALSE is returned. Otherwise, the function
* returns %TRUE.
*
* Returns: When an error occured during the conversion, %FALSE is returned,
* and %TRUE otherwise.
