[Qemu-devel] [PATCH v24 04/31] QemuOpts: change opt->name|str from (const char *) to (char *) |
Date: |
Thu, 3 Apr 2014 17:54:22 +0800 |
qemu_opt_del() already assumes that all QemuOpt instances contain
malloc'd name and value; but it had to cast away const because
opts_start_struct() was doing its own thing and using static storage
instead. By using the correct type and malloced strings everywhere, the
usage of this struct becomes clearer.
