    ************************************************************************
    /tset/POSIX.os/ioprim/write/T.write 2 Failed

    Test Description:
    When nbytes is equal to zero then the file pointer is not moved, zero
    is returned and the st_atime, st_ctime and st_mtime fields are not
    updated. This happens whether the file is created using creat() or
    open() with O_APPEND set.
    Posix Ref: Component WRITE Assertion 6.4.2.2-05(A)

    Test Strategy:
    CREATE new file using creat()
    SAVE timestamps using fsavtimes()
    VERIFY write(fd, buf, 0) returns zero
    VERIFY that the timestamps have not been updated using fchktimes()
    VERIFY lseek(fd, 0, SEEK_END) returns zero
    CLOSE file descriptor using close()
    OPEN file using open() with O_APPEND set
    WRITE some data to file
    REWIND file using lseek(fd, 0, SEEK_SET)
    SAVE timestamps using fsavtimes()
    VERIFY write(fd, buf, 0) returns zero
    VERIFY that the timestamps have not been updated using fchktimes()
    VERIFY lseek(fd, 0, SEEK_CUR) returns zero
    CLOSE file descriptor using close()
    UNLINK file

    Test Information:
    write(fd, buf, 0) with O_APPEND set moved the file pointer from 0 to 26
