linux打印堆栈

为了调试方便,有些时间我们需要打印堆栈信息.

 

#include <execinfo.h>
#include <stdio.h>
#include <stdlib.h>


void print_strace(void)
{
        void *array[10] = {0};
        size_t size;
        char **strings;
        size_t i;
        int nCount = 0;

        size =backtrace(array,10);
        strings = backtrace_symbols(array,size);

        for(i = 0;i<size;i++)
        {
                printf("%s\n",strings[i]);
                if(strstr(strings[i],"ILibWebServer_Release")!=NULL)
                {
                        nCount++;
                }
        }
        free(strings);
}

void fun(void)
{
        print_strace();
}

int main(void)
{
        fun();
        return 0;
}

 

编译时一定要加上参数(-g -rdynamic).

不加-rdynamic的效果就是:

./a.out [0x8048469]
./a.out [0x80484fa]
./a.out [0x8048512]
/lib/libc.so.6(__libc_start_main+0xdc) [0x4b863f2c]
./a.out [0x80483b1]

加-rdynamic的效果就是:

./a.out(print_strace+0x35) [0x8048639]
./a.out(fun+0xb) [0x80486ca]
./a.out(main+0x16) [0x80486e2]
/lib/libc.so.6(__libc_start_main+0xdc) [0x4b863f2c]
./a.out [0x8048581]

呵呵,函数名都打出来了,这是我们想要的.
