Is there a way to use __declspec(align) for for declaring of objects with different type

Question

Is there a way to use __declspec(align) for declaring lot of objects in Visual studio? Sth like:

__declspec(align)
{
int p1;
long p2
}

My question is similar to __declspec(align) for multiple declarations. But this question is for objects with same type.

Answer 1

No, you can't apply a single __declspec(align) to a block of unrelated declarations like this. Each individual declarator statement needs its own __declspec:

Syntax

__declspec( align( # ) ) declarator  

You are probably looking for #pragma pack instead:

Syntax

#pragma pack( [ show ] | [ push | pop ] [, identifier ] , n  )  

For example:

#pragma pack(push, 4)
int p1;
long p2
#pragma pack(pop)

#pragma pack(push, 16)
float rF[4];
float gF[4];
float bF[4];
#pragma pack(pop)

/*
Alternatively:

#pragma pack(push, 16)
typedef float floatArray4[4];
#pragma pack(pop)

floatArray4 rF;
floatArray4 gF;
floatArray4 bF;
