I've got this warning recently (VC++ 2010)

warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators

I'm assuming this is the Critical Section. It's been a while since my Operating Systems course, so I can't really figure out what this means. If I remember right, the Critical Section works with shared resources. So how is this warning related and what does it mean exactly?

LIBCMT.LIB to initialize the CRT related stuffs.... Use mainCRTStartup for entry function, then call _CRT_INIT explicity.

link hello_world.obj Kernel32.lib UCRT.LIB legacy_stdio_definitions.lib LIBCMT.LIB /subsystem:console  /out:hello_world_basic.exe

segment .data
    msg db "Hello world!", 0xd, 0xa, 0

segment .text
global mainCRTStartup
extern ExitProcess
extern _CRT_INIT

extern printf

mainCRTStartup:
    push    rbp
    mov     rbp, rsp
    sub     rsp, 32

    call    _CRT_INIT

    lea     rcx, [msg]
    call    printf

    xor     rax, rax
    call    ExitProcess
    ret

If you don't call _CRT_INIT, the linker will show the warnings about "warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators".
