 Hello Ken,

 {{{
 cat ./hello.c
 #include <unistd.h>
 #include <string.h>
 #include <errno.h>

 int main()
 {
     const char * const msg = "Hello World!\n";
     const char * begin = msg;
     const char * const end = begin + strlen(msg);

     while (begin < end)
     {
         size_t remaining = end - begin;
         ssize_t res = write(STDOUT_FILENO, begin, remaining);
         if (res >= 0)
         {
             begin += res;
             continue; // Let's send the remaining part of this message
         }
         if (EINTR == errno)
         {
             continue; // It's just a signal, try again
         }
         return 1; // It's a real error
     }
     return 0; // OK! Let's celebrate and drink some beer!
 }
