主要使用了getcontext和walkcontext两个函数。 #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <ucontext.h> #include <dlfcn.h> int walker(uintptr_t pc, int sig, void *usrarg) { Dl_info dlip; if(dladdr((void *)pc, &dlip)) { (void)printf(" %08lx %s %s\n", pc, dlip.dli_fname, dlip.dli_sname); return 0; } else { perror("dladdr()"); return -1; } } int bar() { char buf[64]; snprintf(buf, 64, "/bin/pstack %i", getpid()); system(buf); (void)printf("\nprintstack()\n"); printstack(0); ucontext_t ucp; if(getcontext(&ucp)) { perror("\ngetcontext()"); return -1; } else { (void)printf("\nwalkcontext()\n"); return walkcontext(&ucp, &walker, NULL); } } int main(int argc, char *argv[]) { return bar(); }

linux:主要使用backtrace和backtrace_symbols两个函数。 #include <execinfo.h> #include <string> using namespace std; //返回当前堆栈调用列表 string print_trace(int fd, int filter_first_lines) { void *array[MAX_STACK_LAYERS]; size_t size; char **strings; size_t i; string strRet(""); size = backtrace (array, MAX_STACK_LAYERS); strings = backtrace_symbols (array, size); for (i = 0; i < size; i++) { if(i < filter_first_lines) continue; if(fd > 0) { write(fd, strings[i], strlen(strings[i])); write(fd, "\n", 1); } strRet.append(strings[i]); if(i < size-1) strRet.append(1, '\n'); } if(fd > 0) write(fd, "\n", 1); free (strings); return strRet; }
