## Functions

### gstbt_child_bin_add_child ()

    gboolean
    gstbt_child_bin_add_child (GstBtChildBin *self,
                               GstObject *child);

Add the given child to the list of children.

#### Parameters

self | a GObject that implements GstBtChildBin |
child | the GstObject to add as a child |

#### Returns

`TRUE` for success

### gstbt_child_bin_remove_child ()

    gboolean
    gstbt_child_bin_remove_child (GstBtChildBin *self,
                                  GstObject *child);

Remove the given child from the list of children.

#### Parameters

self | a GObject that implements GstBtChildBin |
child | the GstObject to remove from the children |

#### Returns

`TRUE` for success

## Types and Values

### struct GstBtChildBinInterface

    struct GstBtChildBinInterface {
      GTypeInterface parent;

      gboolean (*add_child) (GstBtChildBin *self, GstObject *child);
      gboolean (*remove_child) (GstBtChildBin *self, GstObject *child);
    };
