hi,
does anyone knows if is there a way to make getchar non blocking?

I'm using curses and I'm on linux platform. With a thread version of the same program I have solved my problems with getch and with the timeout function but now the program doesn't work properly and I must use

c=getchar();    
if (c==0) c=getch();

Using timeout(1) makes non blocking only the c=getch part of this code but not the getchar one.

I have tried to solve this problem using this function

int kbhit(void)

{

struct timeval tv;

fd_set read_fd;

tv.tv_sec=0;

tv.tv_usec=0;

FD_ZERO(&read_fd);

FD_SET(0,&read_fd);

if(select(1, &read_fd, NULL, NULL, &tv) == -1)

return 0;

if(FD_ISSET(0,&read_fd))

return 1;

return 0;

}

and this code

if (kbhit()) 
     c = getchar();

but the program doesn't work properly...

Does anyone knows a solution?

I'm 5 days in a row searching of solve this big problem unhappy

does anyone has a idea?

The solution is not to use functions that compromise portability.
