2. attaching async signal (SIGIO) to your STDIN.

Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)
Hello,
i am using the sigaction function to handle the SIGCHLD signal.Is it possible to use a class member function as the handler function (the sa_handler member of the sigaction structure)?
The function's signature is:
void (*sa_handler)(int);so i don't think i can use a static member function... (2 Replies)

poll_keyboard
poll_keyboard(3alleg4) Allegro manual poll_keyboard(3alleg4)NAME
poll_keyboard - Polls the keyboard. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int poll_keyboard();
DESCRIPTION
Wherever possible, Allegro will read the keyboard input asynchronously (ie. from inside an interrupt handler), but on some platforms that
may not be possible, in which case you must call this routine at regular intervals to update the keyboard state variables.
To help you test your keyboard polling code even if you are programming on a platform that doesn't require it, after the first time that
you call this function Allegro will switch into polling mode, so from that point onwards you will have to call this routine in order to get
any keyboard input at all, regardless of whether the current driver actually needs to be polled or not.
The keypressed(), readkey(), and ureadkey() functions call poll_keyboard() automatically, so you only need to use this function when
accessing the key[] array and key_shifts variable.
RETURN VALUE
Returns zero on success, or a negative number on failure (ie. no keyboard driver installed).
