Mixing mmap & malloc appears to be a recipe for much grief. mmap doesn't seem to take much notice of what's already malloced and occasionally drops its region over the top of some already malloced space. I've tried with the addr parameter set to something which is malloced to be the same size as the file being mmaped in, I've tried it set to zero, I've tried doing my mallocing all before the mmap and (where possible) all after. No dice. (For the curious, the application in question is a re-implementation of the doom soundserver which gropes through the wadfile using mmap. I'm re-implementing it so I can send the sounds off to the NAS soundserver) Stephen -- The views expressed above are not those of the Worker's Compensation Board of Queensland, Australia.
