OK fixed that: 
void
process_input(void)
{
  //reads a line from stdin and processes it.
  char buffer[255]; //should be long enough for a single command line
  char rd_buf='a';
  int length,err;
  struct opengl_command *tmp;

  do {
  length=0;
  do {
    err=read(fileno(stdin),&rd_buf,1);
    if(err>=0) length+=err;
      else { fprintf(stderr,"Could not read stdin?\n");
              exit(-1);
            };

//This is a hack to stop process if gnuplot crashes.
    if(!err && check_buffered_input()) 
        {
                fprintf(stderr,"Broken pipe.  Terminating\n");
                exit(-1);
        };
