Subject: lttng-ctl: notifications: use epoll()/poll() instead of select()
X-Git-Tag: v2.11.0-rc3~21
X-Git-Url: http://git.lttng.org/?a=commitdiff_plain;h=06c7582761a17958e9b9df8fd17b22150c563f2b;hp=06c7582761a17958e9b9df8fd17b22150c563f2b;p=lttng-tools.git

lttng-ctl: notifications: use epoll()/poll() instead of select()

The select(2) system call is an ancient ABI limited to processes
containing at most FD_SETSIZE file descriptors overall (typically
1024).

Those notification APIs will fail if the target file descriptor
is above FD_SETSIZE in a process containing many file descriptors.

Never use select, use the lttng epoll/poll wrapper instead.
