stam.h@ 96399

Last change on this file since 96399 was 93468, checked in by vboxsync, 3 years ago
VBoxDbg,VMM/STAM,Main: Converted VBoxDbg to use the VMM function table, extending the STAMR3Enum to include the unit string to avoid needing to call STAMR3GetUnit a lot. The latter would better fit with the XML based viewer, as it only gets the string version of the unit. Had to adjust a user of STAMR3Enum in Main. bugref:10074
