[Qemu-devel] [PATCH 12/13] monitor: hide *cur_mon in monitor_get_fd()

[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

All existing caller are using *cur_mon as its parameter, and *cur_mon
is an internal variable which used inside monitor.c. This patch reduce
the exposing of details in monitor.c, by introduce a new function
monitor_get_fd_cur() and make old one static.
