Code:
 function2()
 
 function1()

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?

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. SEE ALSO
