void use_stdout	(	chars_t	string,

Parameters:

string	text to print

This is a call-back outter function for dumping atom contents to standard output.

void use_stdeof

(

)

This is a call-back inner_eof function for checking standard input.

{
  return feof(stdin)?1:0;
}

char_t use_stdin

(

)

reads a character from standard input

Read a character from the hooked of file stream, which must be ASCII.

This is a call-back inner function for geting urser input.

{
  char_t ch;
  ch = GETCHAR( stdin );
  while( ch=='\r' ) ch = GETCHAR( stdin ); // remove ^M from input, keep ^J
  return ch;
