急!!!!!!!!AIX下怎么跟踪调用函数栈!?

hugbee

大家帮帮忙,AIX下有没有类似Linux下backtrace函数,可以跟踪出函数调用栈的函数!?

Charlemagne

mt__trce(output_fd, 0, NULL, 0);

谢谢Charlemagne ，但是mt__trce在哪个头文件定义？

Charlemagne

mt__trce Subroutine

Purpose
Dumps traceback information into a lightweight core file.

Library
PTools Library (libptools_ptr.a)

Syntax

void mt__trce (int  FileDescriptor, int Signal, struct sigcontext *Context, int Node);

Here is an example fyi...
#cat test.c
//xlc test.c -lptools_ptr
#include <stdio.h>

int testfun1(int* i)
{
   
    mt__trce(2, 0, NULL, 0);
    return (*i)++;
}

int testfun(int* i)
{
    (*i)++;
    return testfun1(i);
}

int main(int argc, char* argv)
{
   int a = 1;
   return testfun(&a);
}   

#xlc test.c -lptools_ptr
[root@test170b:/tmp]#./a.out

truss -o /tmp/a -p PID

不过这个命令只能跟踪系统call
