debug 新方法

直接上代碼吧 debug.h 如下

#ifndef __COMMON_DEBUG__
#define __COMMON_DEBUG__
#include <signal.h>

typedef int signal_t;
typedef void (*SignalHandler)(signal_t sig_no);
typedef void (*SignalHandlerContext)(signal_t sig_no, siginfo_t *info, void *secret);


namespace common{
    class CSignalDebug{
    public:
        void SetHandler(signal_t signo, SignalHandler sig_func);    
        void SetHandler(signal_t signo, SignalHandlerContext sig_func);    
        static void PrintBackStrace(signal_t sig_no, siginfo_t *info, void *secret);    
    };  

};

debug.cc

#include "debug.h"
#include "stdio.h"
#include <execinfo.h>

#include "debug.h"
#include<iostream>
using namespace std;

namespace common{
    

    void CSignalDebug::SetHandler(signal_t signo, SignalHandler sig_func){
            struct sigaction act;
            sigemptyset(&act.sa_mask);
            act.sa_handler = *sig_func;
            sigaction(signo, &act, NULL);
        }   
    
    void CSignalDebug::SetHandler(signal_t signo, SignalHandlerContext sig_func){
            struct sigaction act;
            sigemptyset(&act.sa_mask);
            act.sa_flags = SA_NODEFER | SA_RESETHAND | SA_SIGINFO;
            act.sa_sigaction = *sig_func;
            sigaction(signo, &act, NULL);
        }   

    
    void CSignalDebug:: PrintBackStrace(signal_t sig_no, siginfo_t *info, void *secret){
        void *trace[100];
        int trace_size = 0;
        char **message = NULL;
        trace_size = backtrace(trace, 100);
        message = backtrace_symbols(trace, trace_size);
    }   

        
}
