Re: how to convert a handle to string What Kirants said is correct, if you want to write a handle for some reason to a file you should save it directly as a handle not as a string.

This is accomplished very simply. You put the handles name as the value and for the size param you use sizeof name of handle or HANDLE should also work. Although I dont think that the handle will be of anyuse to you in a file. However this is what you wanted to know NET Framework. How hard would it really be to port to Windows 8? All times are GMT They are all interchangeable, but only if you know what you are doing.

They are not necessarily interchangeable on an instant's notice, because of issues such as buffering. Therefore, unless you understand what needs to be done to flush buffers and maintain consistency in the various file handle images of the file contents and position, you are going to end up in serious trouble. More typically, you have a fresh, newly-opened handle of one type and wish to now associate it with a representation more suitable for your task.

For example, the C library function fopen does a pitiful job of handling file sharing, a concept which was nonexistent on the Unix operating system in which it was first specified.

You want to use the full Win32 file sharing, but don't want to have to do raw WriteFile operations. And maybe you can't because you are retrofitting something into an existing, possibly portable-across-operating-systems source set, and you're writing the OS-specific module.

Keep reading! Note that while the file handles are typically private to a process, the file data that the file handles point to is not. Therefore, processes and threads that share the same file must synchronize their access. For most operations on a file, a process identifies the file through its private pool of handles.
