_EdSelect( ) API Library Routine


void _EdSelect(WHANDLE wh, EDPOS startPos, EDPOS endPos) WHANDLE wh; /* Handle of editing window. / EDPOS startPos; / Beginning offset position of selection. / EDPOS endPos; / Ending offset position of selection. */

void _EdSelect(WHANDLE wh, EDPOS startPos, EDPOS endPos)
WHANDLE wh;            /* Handle of editing window. */
EDPOS startPos;         /* Beginning offset position of selection. */
EDPOS endPos;         /* Ending offset position of selection. */

The following example opens for editing a file specified by a parameter, selects the first character in the file using _EdSelect( ), copies the selection to the clipboard using _EdCopy( ), and pastes it after the second character using _EdPaste( ).
