fdatasync(3C) Standard C Library Functions fdatasync(3C)NAMEfdatasync - synchronize a file's dataSYNOPSIS#include <unistd.h> int fdatasync(int fildes);DESCRIPTIONThe 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 VALUESIf 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.ERRORSThe 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).ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Committed | +-----------------------------+-----------------------------+ |MT-Level |Async-Signal-Safe | +-----------------------------+-----------------------------+ |Standard |See standards(5). | +-----------------------------+-----------------------------+SEE ALSOfcntl(2), open(2), read(2), write(2), fsync(3C), aio_fsync(3C), fcntl.h(3HEAD), attributes(5), standards(5) SunOS 5.11 5 Feb 2008 fdatasync(3C)
