I'm trying to use ultrix curses for some screen handling routines. What I
want to to do is interpret each character as it is typed (so that i can
respond to arrow keys etc.), while allowing typeahead.
The program looks something like this:
main(0
{
/*initialisation*/
crmode();
.
.
.
get_raw_char(str,size,echo_it);
.
.
etc.
nocrmode();
}
get_raw_char(str,size,echo_it)
char *str;
int size,echo_it;
{
int i;
if (echo_it != TRUE)
noecho();
for (i=0;i<size;i++)
{
str[i] = getch();
}
echo();
}
The problem occurs if I try and type ahead more than a minimal amount (1 or
2 characters) the program ignores what is typed. Worse still it misses the
<esc> part of the arrow key sequence resulting in '[B' or similar being
returned.
I've tried replacing [no]crmode() with [no]raw(), but the effect is the
same.
Is there anyway of getting curses to accept typeahead? Or is there a better
way of getting single character input while using curses?
Any help would be greatly appreciated.
Please e-mail any suggestions to me and I'll post a summary, when (if) I get
something working.
