為了調試友善,有些時間我們需要列印堆棧資訊.
Code
#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;
}
編譯時一定要加上參數(-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,函數名都打出來了,這是我們想要的.
