SYNC !!!SYNC NAME SYNOPSIS DESCRIPTION RETURN VALUE CONFORMING TO BUGS SEE ALSO ---- !!NAME sync - commit buffer cache to disk. !!SYNOPSIS __#include __ __int sync(void);__ !!DESCRIPTION __sync__ first commits inodes to buffers, and then buffers to disk. !!RETURN VALUE __sync__ always returns 0. !!CONFORMING TO SVr4, SVID, X/OPEN, BSD 4.3 !!BUGS According to the standard specification (e.g., SVID), __sync()__ schedules the writes, but may return before the actual writing is done. However, since version 1.3.20 Linux does actually wait. (This still does not guarantee data integrity: modern disks have large caches.) !!SEE ALSO bdflush(2), fsync(2), fdatasync(2), update(8), sync(8) ----
