#include <stdio.h>

void main()
  {
    FILE *fp;
    fpos_t position;
    char buffer[80];

    fp = fopen( "file", "r" );
    if( fp != NULL ) {
      fgetpos( fp, &position ); /* get position     */
      fgets( buffer, 80, fp );  /* read record        */
      fsetpos( fp, &position ); /* set position     */
      fgets( buffer, 80, fp );  /* read same record */
      fclose( fp );
    }
  }
