Constant interprocess::os::unix::signal::NUM_REALTIME_SIGNALS

pub const NUM_REALTIME_SIGNALS: u32 = (SIGRTMAX - SIGRTMIN + 1) as u32; // 31u32

How many real-time signals are supported. Remember that real-time signals start from 0, so this number is higher than the highest possible real-time signal by 1.

Platform-specific values for this constant are:

• Linux and NetBSD: 31
• FreeBSD: 62
• Redox: 5 (does not conform with POSIX)
