Yes. For example say you call a bunch of functions or sub-routines in a c-program, they would appear on the call stack in the following order (where function2() is the most recent function to be called, function1() was called before function2() etc... )
Please let me know if that helps in anyway
You are absolutely correct.
A main is also a thread; they way it has a calling sequence to a function, the way a posix thread calls to functions look like.
Ramen: Can't we call epoll()/kqueue() in the threads; why to call in the main thread (in the hi-performing server apps -as you have said) even in the asynchronous nonblocking calls?? I know kqueue() a bit but still not much can we discuss this in the rest of the thread?

explain_malloc_or_die
explain_malloc_or_die(3) Library Functions Manual explain_malloc_or_die(3)NAME
explain_malloc_or_die - Allocate and free dynamic memory and report errors
SYNOPSIS
#include <libexplain/malloc.h>
void *explain_malloc_or_die(size_t size);
DESCRIPTION
The explain_malloc_or_die function is used to call the malloc(3) system call. On failure an explanation will be printed to stderr,
obtained from explain_malloc(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
void *result = explain_malloc_or_die(size);
size The size, exactly as to be passed to the malloc(3) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
