Moves the insertion point to the specified offset position in the file in the specified editing window, unselecting any selected text.

void _EdSetPos(WHANDLE wh, EDPOS thePos)
WHANDLE wh;            /* Handle of editing window. */
EDPOS thePos;               /* Specified offset position. */

Example

The following example opens for editing a file specified by a parameter. Using _EdSetPos(В ), it sets the insertion point to position 19 of the file. It calls _EdGetPos(В ) and inserts some text to verify that the insertion point has been set.
