Re: Is it possible to have two processes communicate in ARM Qemu?


Hi Andrei,

Thanks for your reply. Are there any other QEMU_EXTRA_FLAGS that allows applications to communicate with one another without using bluetooth? Like named pipes in C?

We use QEMU_EXTRA_FLAGS for providing this parameter for QEMU, for
example in bluetooth we may run btproxy on Linux host and
QEMU_EXTRA_FLAGS like following:

QEMU_EXTRA_FLAGS = -serial unix:/tmp/bt-server-bredr
