Question

Define fflush and describe what it does. Define frewind and describe what it does.

Answer 1

Well, good information on all that can be had at the two URLs below. There isn't any frewind in standard ANSI libs, so you may have to find other resources there unless I miss understood or you typoed it. Figure it out from there.

Answer 2

In the C language fflush (File Flush) function causes any unwritten data to be written to a file. If this is not used data will be written when a buffer is full or on using fclose.

frewind - File Rewind - sets the file pointer to the beginning of the file (not standard C?).
