Golang源码之syscall包

go 版本为1.14, Mac电脑, 1.7 GHz 四核Intel Core i7

在src/syscall/路径下,打开zerrors_darwin_amd64.go文件,

第1245行:

// Signals
const (
	SIGABRT   = Signal(0x6) //十进制数6
	SIGALRM   = Signal(0xe) //14
	SIGBUS    = Signal(0xa) //10

)

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31, 共31个

SIGIOT和SIGABRT都是6,二者同义
