I'm a little tired and haven't perused the ROM code in several months, but this should be rather straightforward. You're gonna want to have an OBJ_INDEX_DATA pointer and use it to loop through all the objects read in from the area files. If memory serves me, it's a hash table. So you'll either want to do something like loop through the VNUMs calling some function to return a pointer to a given object (slow - 0(n^2) probably if you are grabbing them based on VNUM) or loop through the hash table manually (O(n) since you're ignoring order this way). Then it's just bit comparisons. You should already have some function able to spit out immunities for a given object in handler.c, since the stat functions display such information now. Either use this or modify it to suit your needs. Or if you don't have one, just use the bitmask macros defined in merc.h to check for immunities. Having said that, unless you need to run this command in real time, I would probably create a function like this that runs during bootup of the mud and dumps the results to a CSV that I could parse or import into a spreadsheet. The reason I say that is the data won't change very often, and the hash table isn't sorted to the best of my memory, so it'd be slow to do it real time, especially on arbitrarily large data sets. Also, if you dump to a CSV you can do all kinds of sorting and filtering after the fact in the program of your choice. Potato.
