A little detour from your question, you may want to check both your addr and len fed to mmap, because it want your required address to be page-aligned. From the mmap () documentation that tells you. Here is my code: After the mmap () call has returned, the file descriptor, fd, can be closed immediately without invalidating the mapping. EINVAL The addr argument (if MAP_FIXED was specified) or off is not a multiple of the page size as returned by sysconf(), or are considered invalid by the implementation.
