### Method

# Gtk LevelBaradd_offset_value

#### Declaration [src]

    void
    gtk_level_bar_add_offset_value (
      GtkLevelBar* self,
      const char* name,

    )

#### Description [src]

If another offset marker named `name` exists, its value will be replaced by `value`.

#### Parameters

`name`

  Type: `const char*`

  The name of the new offset.

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

`value`

  Type: `double`

  The value for the new offset.
