| |
Let me get this straight...
Buffered is when a program writes to a file and it is buffered.
Cached is for when a program reads from a file.
Is that right?
Also, if one process has a file mmap()ed and another process is writing to it, is the other process directly writing to the same pages? Or are they kept in sync some other way?
Basically, when you mmap() a file, are the actual pages in the buffer cache be mapped into your address space?
Please CC any replies to me.
