Hello,

Has kbhit() problem when interrupted by SIGALRM (generated with
setitimer(), not with alarm()) ? It seem to hang-on and simple never
return. It could be a bug of my program or there are known problems on
kbhit() ?

(I know, the signal delivering is delayed during DOS system call. That's
why I'm using a kbhit() based loop instead of a getch()).

Note:
- Running under Win95 DOS Box (I know, uclock() could fail under Win95).

- DJGPP v2.02
- setitimer() patched as suggested me by Eli Zaretskii (BTW, thanks for
the code)

Thanks in advance,

Alberto.

p.s.: I can post a detailed problem report if required
