Hello, I wrote an mmap() interface for a USB device. But when I made a call to it using mmap(), I saw that mmap interface is called 3-4 times. The calls are being made from within mmap() i.e. sys/vm/vm_mmap.c. Can someone tell me if there is something like a re-try going on for some reason? From userspace, I called it as addr = mmap(NULL, 1024, PROT_READ, MAP_SHARED, fd, 0); The version of OS is Freebsd 5.3(stable). thanks -kamal
