GWEN_Tag16_StartTagInBuffer()

int GWEN_Tag16_StartTagInBuffer	(	unsigned int	tagType,
		GWEN_BUFFER *	buf )

Use this function together with GWEN_Tag16_EndTagInBuffer to create complex tags in a buffer. This can be used to cascade tags into a buffer.

Internally this function writes the begin of a TAG16 structure into buffer. After that you can add as many bytes as you like. Finally call GWEN_Tag16_EndTagInBuffer to finish the tag by correcting the size element of the tag16 in the buffer.

Returns

start position of the newly created tag in buffer (<0 on error)

Parameters

tagType	8-bit type code/name/id of the tag (meaning of this code is up to the caller)
buf	buffer to write into
