[Qemu-devel] [PATCH 17/29] qemu-option: qemu_opt_parse(): use error_set() |
Date: |
Tue, 5 Jun 2012 14:24:56 -0300 |
The functions opt_set() and qemu_opts_validate() both call qemu_opt_parse(),
but their callers expect QError semantics. Thus, both functions call
qerro_report_err() to keep the expected semantics.
