Which of the following statements is true about using dprintf in relation to file descriptors and fdopen? dprintf automatically handles file descriptors and removes the need to call fdopen to convert a file descriptor into a file pointer for use with fprintf. dprintf requires that a file descriptor be converted to a file pointer using fdopen before it can be used. fdopen is needed to convert a file descriptor into a file pointer when using dprintf for formatted output. dprintf is equivalent to fprintf and requires fdopen to function correctly with file descriptors.
