NAME
fdatasync - synchronize a file's data SYNOPSIS
#include <unistd.h> int fdatasync(int fildes); DESCRIPTION
The fdatasync() function forces all currently queued I/O operations associated with the file indicated by file descriptor fildes to the synchronized I/O completion state. The functionality is as described for fsync(3C) (with the symbol _XOPEN_REALTIME defined), with the exception that all I/O operations are completed as defined for synchronised I/O data integrity completion. RETURN VALUES
If successful, the fdatasync() function returns 0. Otherwise, the function returns -1 and sets errno to indicate the error. If the fdata- sync() function fails, outstanding I/O operations are not guaranteed to have been completed. ERRORS
The fdatasync() function will fail if: EBADF The fildes argument is not a valid file descriptor open for writing. EINVAL The system does not support synchronized I/O for this file. ENOSYS The function fdatasync() is not supported by the system. In the event that any of the queued I/O operations fail, fdatasync() returns the error conditions defined for read(2) and write(2).
