dwg_dynapi_common_set_value()

bool dwg_dynapi_common_set_value	(	void *restrict	_obj,
		const char *restrict	fieldname,
		const void *restrict	value,
		const bool	is_utf8
	)

Sets the common ENTITY or OBJECT.fieldname to a value. A malloc'ed struct is passed by ptr, not by the content. A non-malloc'ed struct is set by content. Arrays or strings must be malloced before. We just set the new pointer, the old value will be freed. If is_utf8 is set, the given value is a UTF-8 string, and will be converted to TV or TU.

dwg_dynapi_common_utf8text()

bool dwg_dynapi_common_utf8text	(	void *restrict	_obj,
		const char *restrict	fieldname,

		void *restrict	out,
		Dwg_DYNAPI_field *restrict	fp
	)

Returns the common ENTITY|OBJECT.fieldname value in out. _obj is the Dwg_Entity_ENTITY or Dwg_Object_OBJECT struct with the specific fields. The optional Dwg_DYNAPI_field *fp is filled with the field types from dynapi.c

		const char *restrict	dxfname,
		const char *restrict	fieldname,
		const void *restrict	value,
		const bool	is_utf8
	)

Sets the ENTITY.fieldname to a value. A malloc'ed struct is passed by ptr, not by the content. A non-malloc'ed struct is set by content. Arrays or strings must be malloced before. We just set the new pointer, the old value will be freed. If is_utf8 is set, the given value is a UTF-8 string, and will be converted to TV or TU.

		char **restrict	textp,
		int *	isnewp,
		Dwg_DYNAPI_field *restrict	fp
	)

Returns the ENTITY|OBJECT.fieldname text value in textp as utf-8. entity is the Dwg_Entity_ENTITY or Dwg_Object_OBJECT struct with the specific fields. The optional Dwg_DYNAPI_field *fp is filled with the field types from dynapi.c With DWG's since r2007+ creates a fresh UTF-8 conversion from the UTF-16 wchar value (which needs to be free'd), with older DWG's or with TV, TF or TFF returns the unconverted text value. Only valid for text fields. isnew is set to 1 if textp is freshly malloced (r2007+), otherwise 0

dwg_dynapi_entity_value()

bool dwg_dynapi_entity_value	(	void *restrict	entity,
		const char *restrict	dxfname,

char* dwg_dynapi_handle_name	(	const Dwg_Data *restrict	dwg,
		Dwg_Object_Ref *restrict	hdl,
		int *	alloced
	)

Checks if the handle hdl points an object or entity with a name field, and returns it if so. Converted to UTF8 for r2007+ wide-strings. Sets alloced if the returned string is freshly malloc'd.
