ffssyynncc - synchronize a file's incore state with that on disk

ffssyynncc(_i_n_t _f_d)
DDEESSCCRRIIPPTTIIOONN
FFssyynncc() causes all modified data and attributes of _f_d to be moved to a
permanent storage device. This normally results in all incore modified
copies of buffers for the associated file to be written to a disk.
FFssyynncc() should be used by programs that require a file to be in a known
state, for example, in building a simple transaction facility.
RREETTUURRNN VVAALLUUEESS
A 0 value is returned on success. A 1 value indicates an error.
EERRRROORRSS
The ffssyynncc() fails if:
[EBADF] _F_d is not a valid descriptor.
[EINVAL] _F_d refers to a socket, not to a file.
[EIO] An I/O error occurred while reading from or writing to the
file system.
