C TO asm [NASM]

I am stuck - i cannot find answer in google or any where else -

how can I pass values to my C code from asm ??

I am compiling my both C code and ASM code to .obj file and linking the mess together . but i cannot find a way pass values to my c code and return value
Thx for help

The EAX register is commonly where values are stored on 32-bit machines once a function has returned.

So,

Code:

---

; ASM
ASMFunction proc
mov eax, 1234
ASMFunction endp

// C
void CFunction()
{
    int blah = ASMFunction();
}

---

Passing values to functions is simple enough.. you just need to make sure the data types are the same size/type:

Code:

---

; ASM
AddASM proc
LOCAL arg1:DWORD,arg2:DWORD
pop arg2
pop arg1

add arg1, arg2

mov eax, arg1

ret
AddASM endp

// C
void AddC(int num1, int num2)
{
    return AddASM(num1, num2);
}
