Linuxカーネルで独自のカスタムシグナルを作成する

Question

私はSIGUSR1とSIGUSR2（または他の標準シグナル）とは別に独自のカスタム名前付きシグナルを定義したいと思います。 これについてはどうすればよいですか？

http://man7.org/linux/man-pages/man7/signal.7.htmlは、real time signalsを定義できますが、定義済みの意味はありません。追加するものはほとんどありません

The range of supported real-time signals 
    is defined by the macros SIGRTMIN and SIGRTMAX. POSIX.1-2001 
    requires that an implementation support at least _POSIX_RTSIG_MAX (8) 
    real-time signals. 

    The Linux kernel supports a range of 33 different real-time signals, 
    numbered 32 to 64. However, the glibc POSIX threads implementation 
    internally uses two (for NPTL) or three (for LinuxThreads) real-time 
    signals (see pthreads(7)), and adjusts the value of SIGRTMIN suitably 
    (to 34 or 35). Because the range of available real-time signals 
    varies according to the glibc threading implementation (and this 
    variation can occur at run time according to the available kernel and 
    glibc), and indeed the range of real-time signals varies across UNIX 
    systems, programs should never refer to real-time signals using hard- 
    coded numbers, but instead should always refer to real-time signals 
    using the notation SIGRTMIN+n, and include suitable (run-time) checks 
    that SIGRTMIN+n does not exceed SIGRTMAX. 

：SIGRTMIN+n < SIGRTMAXSIGRTMIN+nを使用しています。コンパイル時のチェックを行います（つまり、libcの実装よりも多くの信号が必要な場合は問題になります）。

何かのようなものがある#define SIGRUBBERDUCK (SIGRTMIN+3)
