After testing on msvc8, I found:
- Parse GetCommandLine() to argc and argv
- Standard C Library initialization
- C++ Constructor of global variables
These three things are called before entering main().
My questions are:
- Will this execution order be different when I porting my program to different compiler (gcc or armcc), or different platform?
- What stuff does Standard C Library initialization do? So far I know setlocale() is a must.
- Is it safe to call standard C functions inside C++ constructor of global variables?
