Segfault about i3blocks HOT 2 CLOSED

Hi @sanpii ,

This is normal if you run i3blocks outside i3bar. This is because the stdin receives an EOF and thus triggers the SIGIO signal (meaning stdin is ready to be read). The handle_click() function assumes that there's a json string to read. If you use i3blocks within i3 you won't have any issue (hopefully).

But this is a good point, maybe I should disable the stdin reading when the I/O unit is a tty.

Using atoi() is safe here, as I know my input (known formatted json string). But you are right, I will definitely use strtol() in the future if I need to make the json parsing more robust.

It’s a good idea to test my configuration, i3status displays an error and I couldn’t know why.
