[Linux]Linux下signalfunction传参⽅式 This is a really old question but I think I can show you a nice trick that would have answered your problem. No need to use sigqueue or whatever.I also dislike the use of globals variables so I had to find a clever way, in my case, to send a...
signal(SIGWHATEVER, (void(*)(int))sighandler) sighandler(FAKE_SIGNAL, your_ptr); In your sighandler func: intsighandler(constintsignal,void*ptr){staticmy_struct saved =NULL;if(saved ==NULL) saved = ptr;if(signal == SIGNALWHATEVER)// DO YOUR STUFF OR FREE YOUR PTRreturn(0); }...
查到的有个这:typedef void (*sighandler_t)(int); 《===》typedef void (*)(int) sighandler_t; 但是我在Linux环境下这样测试: void (*)(int ,char *) p; 这样会报错,错误提示是: test2.c: In function ‘main’: test2.c:14:9: error: expected identifier or ‘(’ before ‘)’ token te...
SIGXFSZ, and (on architectures other than SPARC and MIPS) SIGBUS was to terminate the process (without a core dump). (On some other Unix systems the default action for SIGXCPU and SIGXFSZ is to terminate the process without a core dump.) Linux 2.4 conforms to the POSIX.1-2001 requireme...

Not used starting with Oracle Solaris 10 reserved on Linux. (Configurable) SIGUSR2 This signal is used internally. Not used starting with Oracle Solaris 10 operating system. (Configurable) SIGABRT The HotSpot VM does not handle this signal. Instead it calls the abort function after fatal error ...
Ignoring signals and restoring original signal handler function sigaction() sigaction()in action Conclusion IntroductionBACK TO TOC Perhaps any engineer developing for Linux encounters this problem. What’s is the right way to terminate the program? What are the ways to receive notifications from opera...
信号在内核中并没有用特别复杂的数据结构来表示,只是用一个代号一样的数字来标识不同的信号。Linux ...
