	{
	BITMAP Bitmap;

	unsigned int bitmap_bytes_per_pixel = 4;
	unsigned int bitmap_scanline_size = (((Bitmap.bmWidth * bitmap_bytes_per_pixel) + (4 - 1)) & ~(4 - 1));

Ssh connection with file-serving via lib-ssh and NFSv2. Can be used connect to linux-based target machine from windows, on the same network though, and execute file-served files. Example usage: -t 192.168.0.1 -u user -p 22 -cwd "myworkingdirectoy" -cmd "./window". Intended for serving and executing cross compiled binaries.

	#include <libssh/libssh.h>
	#include <stdlib.h>

	#include <errno.h>
	#include <string.h>
