Another answer to an old thread.
When I need to do this, I usually just use system() and pstack
So something like this:
#include <sys/types.h>
#include <unistd.h>
#include <string>
#include <sstream>
#include <cstdlib>
void f()
{
pid_t myPid = getpid();
std::string pstackCommand = "pstack ";
std::stringstream ss;
ss << myPid;
pstackCommand += ss.str();
system(pstackCommand.c_str());
}
void g()
{
f();
}
void h()
{
g();
}
int main()
{
h();
}
This outputs
#0 0x00002aaaab62d61e in waitpid () from /lib64/libc.so.6
#1 0x00002aaaab5bf609 in do_system () from /lib64/libc.so.6
#2 0x0000000000400c3c in f() ()
#3 0x0000000000400cc5 in g() ()
#4 0x0000000000400cd1 in h() ()
#5 0x0000000000400cdd in main ()
This should work on Linux, FreeBSD and Solaris. I don't think that macOS has pstack or a simple equivalent, but this thread seems to have an alternative.
If you are using C, then you will need to use C string functions.
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
void f()
{
pid_t myPid = getpid();
/*
length of command 7 for 'pstack ', 7 for the PID, 1 for nul
*/
char pstackCommand[7+7+1];
sprintf(pstackCommand, "pstack %d", (int)myPid);
system(pstackCommand);
}
I've used 7 for the max number of digits in the PID, based on this post.
