Name
       fseek, ftell, rewind - reposition a file pointer in a stream

Syntax
       #include <stdio.h>

       int fseek(stream, offset, ptrname)
       FILE *stream;
       long offset;
       int ptrname;

       long ftell(stream)
       FILE *stream;

       void rewind(stream)
       FILE *stream;

Description
       The  function  sets  the  position  of the next input or output operation on the stream.  The new position is at the signed distance offset
       bytes from the beginning, the current position, or the end of the file, according as ptrname has the value SEEK_SET, SEEK_CUR, or SEEK_END.

       The function undoes any effects of

       The function returns the current value of the offset relative to the beginning of the file associated with the named stream.   It  is  mea-
       sured in bytes and is the only foolproof way to obtain an offset for

       The (stream) function is equivalent to (stream , 0L, 0, SEEK_SET), except that no value is returned.

Return Values
       The function returns -1 for improper seeks, otherwise 0.
