rewind


Sets the position indicator associated with stream to the beginning of the file. The end-of-file and error internal indicators associated to the stream are cleared after a successful call to this function, and all effects from previous calls to ungetc on this stream are dropped.

Syntax:
void rewind ( FILE * stream );


Example:

#include 

int main ()
{
  int n;
  FILE * pFile;
  char buffer [27];

  pFile = fopen ("myfile.txt","w+");
  for ( n='A' ; n<='z' ; n++)
    fputc ( n, pfile);
  rewind (pfile);
  fread (buffer,1,26,pfile);
  fclose (pfile);
  buffer[26]='\0';
  puts (buffer);
  return 0;
}
