Question

I’m writting a program in c# that uses a C++ library, and for some reason I need to allocate an unmanaged buffer to pass it to the lib. Is there a way to do this in c# ?
Basically I would just need to do a malloc in C#…

Thanks

Try something like this:

using System;
using System.Runtime.InteropServices;

class Example
{
    static void Main()
    {
        IntPtr pointer = Marshal.AllocHGlobal(1024);
    }
}

This uses the Marshal.AllocHGlobal method:

Allocates memory from the unmanaged memory of the process by using the specified number of bytes.
