_GetItemCmdKey( ) API Library Routine

Copies the displayed keyboard shortcut string for the specified menu item to the buffer pointed to by the text parameter.

int _GetItemCmdKey(MENUID menuid, ITEMID itemid, char FAR *text)
MENUID menuid;            /* Menu identifier. */
ITEMID itemid;            /* Menu item identifier. */
char FAR *text;            /* Where to store the shortcut string. */

Remarks

_GetItemCmdKey( ) returns the internal keyboard code for the keyboard shortcut. If there is no keyboard shortcut for the specified menu item, _GetItemCmdKey( ) returns 0.

Example

The following example creates a menu with three items, setting up a keyboard shortcut for each item. It uses _GetItemCmdKey( ) to display the shortcut keys.
