Using SunOS 4.x, is there a way to insure that a disk file and a
segment of memory mapped with mmap are consistent - i.e. to guarantee
that all writes to the memory segment are on disk?  I would like
something like fflush but fflush wants a FILE * parameter and mmap
wants an int fd.

Please address any replies to:
