#pragma managed/unmanaged

[Nish Nishant]

I discovered that you cannot use #pragma unmanaged for a member function of a managed class, even though the member function uses only unmanaged calls. Thus I have concluded that you can use #pragma unmanaged only for unmanaged global functions or for unmanaged classes. But then, what's the bloody point, since unmanaged code will get compiled to native code anyway! :confused: Nish

Thats the whole point, you can call the x86 code from managed code :)

#pragma managed
public __gc class MyClass
{
// other garbage

void DoLotsOfUnmanagedThings()
{
unmanagedCall();
}
};

#pragma unmanaged

void unmanagedCall()
{
// 100% unmanaged code goes here
}

Well, when it sees a fuilly unmanaged function, why doesn't it auto-apply #pragma unmanaged to that block? Nish

Managed Code - Code that compiles into IL (atleast in the first version of CLR in the next version it would be possible to have IL unmanaged functions) 2. Unmanaged Code - Code that compiles into native processor's instructions So you see there is nothing called an unmanaged function before anything gets compiled. It is perfectly legal to have global functions in managed code. ILASM can create and use it( may be VB.NET).
