search for: optionalheader

Hi,I am planting wine to a new Operating System. I found that in libs/wine/loader.c ->map_dll ,a piece of code like: Code: /* module address must be aligned on 64K boundary */ addr = (BYTE *)((nt_descr->OptionalHeader.ImageBase + 0xffff) & ~0xffff); if (wine_anon_mmap( addr, page_size, PROT_READ|PROT_WRITE, MAP_FIXED ) != addr) return NULL; My questing is the so (such as ntdll.dll.so,kernel32.dll.so) is already loaded ,and can be accessed ,why wine_anon_mmap is needed here? Thank you.
