| |
Hi, mmap() creates a mmaped memory associated with a physical file. If a process updates the mmaped memory, Linux will updates the file "automatically". If this is the case, why do we need msync()? If this is not the case, what is the interval between 2 "WRITE" (IO request operation) request to the physical file because it really updates the physical file somehow even without msync(). Any comments about how mmap() works will be appreciated. Thanks.
Jerry
