7.1.1 Low level functions

These functions let the caller create nodes or access nodes easier.

• SGFNode *sgfNewNode(void)

  Allocate and return a new instance of SGFNode. The node is cleared.

• SGFProperty *sgfMkProperty(const char *name, const char *value, SGFNode *node, SGFProperty *last)

  Allocate and return a new instance of SGFProperty. The name should be 1 or 2 characters long. This function should probably not be used directly. Instead, use the sgfAddProperty functions.

• SGFNode *sgfPrev(SGFNode *node)

  Return the previous node in a chain. This is done by going to the parent node and then search through the children until the same node is found. If there is no previous node, NULL is returned.

• SGFNode *sgfRoot(SGFNode *node)

  Return the root of the tree. If node already is the root, node itself is returned.
