.SH DESCRIPTION
|
||
|
|
.B Sync
|
||
|
|
causes all information in the file system
|
||
|
|
buffers that should be on disk to be written out.
|
||
|
|
This includes modified super blocks,
|
||
|
|
modified i-nodes, and delayed block I/O.

|
Fsync
|
||
|
|
does the same thing, but only for the blocks associated with a specific
|
||
|
|
file descriptor. Under minix, currently the two calls do the same thing.
