dbgmod.cpp@ 78365

Last change on this file since 78365 was 77981, checked in by vboxsync, 6 years ago
Runtime/dbgmod.cpp: Make RTDbgModCreateFromMap(), RTDbgModCreateFromImage(), rtDbgModFromPeImageOpenCallback() and rtDbgModFromMachOImageOpenDsymMachOCallback() return VERR_DBG_NO_MATCHING_INTERPRETER (like it was probably intended to) if no matching backend was found instead of just returning the error code (like VERR_EOF) of the last backend tried
