Manual page for FSYNC(2)
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 modified 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.
