Re: [PATCH v14 13/17] qemu-sockets: move and rename SocketAddress_to_str()

Hi

Rename SocketAddress_to_str() to socket_uri() and move it to
util/qemu-sockets.c close to socket_parse().

socket_uri() generates a string from a SocketAddress while
socket_parse() generates a SocketAddress from a string.

Tbh, as we are renaming functions here, I would follow good glib/C conventions and use the type name in lower case as prefix. I would also not use "URI", which should be reserved for RFC3986 compliant forms.

So instead, I'd suggest to rename to:

char *socket_address_to_string(SocketAddress *addr);

SocketAddress *socket_address_new_from_string(const char *str, Error **errp)

my 2c
