[Qemu-devel] [PATCH v3 3/4] net/socket: Convert error report message to Error |
|
Date: |
Fri, 9 Jun 2017 18:01:47 +0800 |
Currently, net_socket_mcast_create(), net_socket_fd_init_dgram() and
net_socket_fd_init() use the function such as fprintf(), perror() to
report an error message.
Now, convert these functions to Error.
