Please see attached main.c for my sample code.
I don't know about the above error, but the way you've used
copy-device-to-file is clearly wrong:
guestfs_mount (g, "/dev/sda1", "/");
//guestfs_mount_local (g, "/home/mohsin/VHD/");
guestfs_ls(g, "/");
guestfs_copy_device_to_file(g, "/dev/sda1/file-to extract.exe",
"/abc.exe");
It's actually not clear to me what you're trying to achieve here.
Download the file to the local host? If so use guestfs_download:
guestfs_download (g, "/file-to-extract.exe", "local-file.exe");
BTW you should check for errors from C API calls.
