L_INT EXT_FUNCTION L_InsertMarker(hMarkers, uIndex, uMarker, uMarkerSize, pMarkerData)

HANDLE hMarkers;	/* marker handle */
L_UINT uIndex;	/* position at which to insert the marker */
L_UINT uMarker;	/* marker’s type */
L_UINT uMarkerSize;	/* marker’s data size */
L_VOID L_FAR * pMarkerData;	/* marker’s data */

Inserts a marker in a marker collection.

Parameter	Description
hMarkers	Handle to a collection of metadata markers. This handle is created by either the L_LoadMarkers function or the L_CreateMarkers function.
uIndex	Position in the list at which to insert the marker. Use 0xFFFFFFFF to append the marker to the end of the list. If there are fewer than uIndex markers in the collection, the marker will be appended to the end of the list.
	Use zero-based indexing. For example, if there are 10 markers in a list, the index of the last one is 9. If you insert a marker within a list, the indexes of other markers change to accommodate the insertion.
uMarker	Value that represents the type of marker to insert. Recommended values are between 0xE0 and 0xFE. Other values are possible, but before using other values, study the JPEG specs to determine which markers are allowed.
uMarkerSize	The size of the marker data, in bytes. This must be between 0 and 0xFFFD.
pMarkerData	Pointer to the marker data. This parameter is needed only if uMarkerSize > 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

You can insert a marker anywhere in the marker collection.
