Subject: gui: Check stdin for readability.
X-Git-Tag: v0.4.13~33^2~10
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=d7562ba640e30ac4bf1160509f4c2f705363d53f

gui: Check stdin for readability.

If the select_loop of para_gui runs in getch or command mode we
currently wait a full timeout period before checking for pending
input.

This patch adds stdin to the set of file descriptors monitored by
select so that a key press causes select() to return immediately.
