• getc FILEHANDLE

• getc

  Returns the next character from the input file attached to FILEHANDLE,or the undefined value at end of file or if there was an error (inthe latter case $! is set). If FILEHANDLE is omitted, reads fromSTDIN. This is not particularly efficient. However, it cannot beused by itself to fetch single characters without waiting for the userto hit enter. For that, try something more like:

   if ($BSD_STYLE) {
   
   system "stty cbreak </dev/tty >/dev/tty 2>&1";
   
   }
   
   else {
   
   system "stty", '-icanon', 'eol', "\001";
   
   }
   
   
   $key = getc(STDIN);
   
   
   if ($BSD_STYLE) {
   
   system "stty -cbreak </dev/tty >/dev/tty 2>&1";
   
   }
   
   else {
   
   system 'stty', 'icanon', 'eol', '^@'; # ASCII NUL
   
   }
   
   print "\n";
   

  Determination of whether $BSD_STYLE should be setis left as an exercise to the reader.
