FSYNC(2)							System Calls Manual							  FSYNC(2)

NAME
fsync - synchronize a file's in-core state with that on disk
SYNOPSIS
fsync(fd) int fd;
DESCRIPTION
Fsync causes all modified data and attributes of fd to be moved to a permanent storage device. This normally results in all in-core modi- fied copies of buffers for the associated file to be written to a disk. Fsync should be used by programs that require a file to be in a known state, for example, in building a simple transaction facility.
RETURN VALUE
A 0 value is returned on success. A -1 value indicates an error.
ERRORS
The fsync fails if: [EBADF] Fd is not a valid descriptor. [EINVAL] Fd refers to a socket, not to a file. [EIO] An I/O error occurred while reading from or writing to the file system.
