Pass parameter to a thread

[binks]

Hi, I'm trying to pass a parameter to a thread, by using CreateThread(). Unfortunately, you have to pass LPVOID or void* as it's only parameter.

I'm trying to pass a structure to it, which should then be passed to another function to handle the data. I would make the structure a global, but it must be defined in a separate function I have.

I read somewhere that

if (sizeof(DATA) <= sizeof(void *))

then you can just cast it as a void*, but I don't know how to do that.

The structure is made like so

Header

struct Download
{
       char name[56];
       char outName[16];
};

Main Prog

int num_files;
...
num_files = x;
...
struct Download file[num_files];

Thanks for the help!
