From e4c8f004c55d9da3eae3e14df740238bf805b5d6 Mon Sep 17 00:00:00 2001 From: Amos Kong Date: Fri, 31 Aug 2012 10:56:26 +0800 Subject: [PATCH] qapi: convert sendkey Convert 'sendkey' to use QAPI. QAPI passes key's index of mapping table to qmp_send_key(), not keycode. So we use help functions to convert key/code to index of key_defs, and 'index' will be converted to 'keycode' inside qmp_send_key(). For qmp, QAPI would check invalid key and raise error. For hmp, invalid key is checked in hmp_send_key(). 'send-key' of QMP doesn't support key in hexadecimal format.
