dbgf.h

Last change on this file was 102092, checked in by vboxsync, 7 months ago
VMM/DBGF,DBGC,Main: Added DBGFR3RegNmQueryEx and fixed some issues with DBGFR3RegNmQueryAll that lead to assertions in Main and empty entries in VBoxManage output. Extended the 'r' and 'rg' debugger commands to make use of the two APIs, the first by appending '.' to a register (e.g. r @cr0.) and the latter by using 'all' as the register name.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
