问题描述
信号似乎是应该在概念上简单且易于解释的那些领域之一，但是我从来没有遇到过既全面，明晰又最新的资料.在某种程度上，这似乎是由于历史原因，许多规则例外，不同的编程标准，混乱的线程，实时的添加等等.
Signals seem to be one of those areas that should be conceptually simple and easy to explain but I have never come across one source that is both comprehensive, lucidly written, and up to date. In part this seems to be because of historical cruft, lots of exceptions to rules, different programming standards, the confusion threads throw into the mix, real-time additions, etc.
关于unix/linux/posix信号，您写得最好，最完整的源代码是什么?网站，书籍，石碑等均可.
What's your best written, most complete source on unix/linux/posix signals? Web sites, books, stone tablets, whatever, are acceptable.
推荐答案
回复:检查手册页的注释:每当遇到手册页故障(不清晰或不完整)时，我都会使用OpenBSD的版本.十分之九，这至少是昼夜差异.
Re: the comments to check man pages: Whenever I encounter man page failure (wrt either lucidity or completeness), I hit up OpenBSD's version. At least nine times out of ten, it's a night and day difference.
因此，在这种情况下，我的建议是 man sigaction & man信号.
So my suggestion in this case is man sigaction & man signal.
