To see the commit logs for this use either cvsweb or cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files. In general this provides a generic interface for logging. logfunctions:: is a class that is inherited by some classes, and also . allocated as a standalone global called 'genlog'. All logging uses . one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this . class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros . respectively. . . An example usage: . BX_INFO(("Hello, World!\n")); iofunctions:: is a class that is allocated once by default, and assigned as the iofunction of each logfunctions instance. It is this class that maintains the file descriptor and other output related code, at this point using vfprintf(). At some future point, someone may choose to write a gui 'console' for bochs to which messages would be redirected simply by assigning a different iofunction class to the various logfunctions objects. More cleanup is coming, but this works for now. If you want to see alot of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1. Comments, bugs, flames, to me: todd@fries.net
