Or even simpler guys, this is probably more portable :)
int main()
{
extern char **environ;
char *** argvp;
char ** argv;
char * s;
void * p;
asm ("mov %%esp, %0" : "=r" (p));
argvp = p;
while (*argvp != environ)
argvp++;
argvp--;
argv = *argvp;
for (s = *argv ; s ; s = *++argv)
printf("%s\n", s);
return 0;
}
