Function cmark_gfm_sys::cmark_parser_add_child

pub unsafe extern "C" fn cmark_parser_add_child(
    parser: *mut cmark_parser, 
    parent: *mut cmark_node, 
    block_type: cmark_node_type, 
    start_column: c_int
) -> *mut cmark_node

Add a child to 'parent' during the parsing process.

If 'parent' isn't the kind of node that can accept this child, this function will back up till it hits a node that can, closing blocks as appropriate.
