+
+These functions provide access to some useful capabilities on Windows
+platforms. Some higher-level modules use these functions to build the
+Windows implementations of their services. For example, the
+\refmodule{getpass} module uses this in the implementation of the
+\function{getpass()} function.
+
+Further documentation on these functions can be found in the Platform
+API documentation.
+
+
+\subsection{File Operations \label{msvcrt-files}}
+
+\begin{funcdesc}{locking}{fd, mode, nbytes}
+ Lock part of a file based on a file descriptor from the C runtime.
+ Raises \exception{IOError} on failure.
+\end{funcdesc}
+
+\begin{funcdesc}{setmode}{fd, flags}
+ Set the line-end translation mode for the file descriptor \var{fd}.
+ To set it to text mode, \var{flags} should be \constant{_O_TEXT};
+ for binary, it should be \constant{_O_BINARY}.
+\end{funcdesc}
+
+\begin{funcdesc}{open_osfhandle}{handle, flags}
+ Create a C runtime file descriptor from the file handle
+ \var{handle}. The \var{flags} parameter should be a bit-wise OR of
+ \constant{_O_APPEND}, \constant{_O_RDONLY}, and \constant{_O_TEXT}.
+ The returned file descriptor may be used as a parameter to
+ \function{os.fdopen()} to create a file object.
+\end{funcdesc}
+
+\begin{funcdesc}{get_osfhandle}{fd}
+ Return the file handle for the file descriptor \var{fd}. Raises
+ \exception{IOError} if \var{fd} is not recognized.
+\end{funcdesc}
+
+
+\subsection{Console I/O \label{msvcrt-console}}
+
+\begin{funcdesc}{kbhit}{}
+ Return true if a keypress is waiting to be read.
+\end{funcdesc}
+
+\begin{funcdesc}{getch}{}
+ Read a keypress and return the resulting character. Nothing is
+ echoed to the console. This call will block if a keypress is not
+ already available, but will not wait for \kbd{Enter} to be pressed.
+ If the pressed key was a special function key, this will return
+ \code{'\e000'} or \code{'\e xe0'}; the next call will return the
+ keycode. The \kbd{Control-C} keypress cannot be read with this
+ function.
+\end{funcdesc}
+
+\begin{funcdesc}{getche}{}
+ Similar to \function{getch()}, but the keypress will be echoed if it
+ represents a printable character.
+\end{funcdesc}
+
+\begin{funcdesc}{putch}{char}
+ Print the character \var{char} to the console without buffering.
+\end{funcdesc}
+
+\begin{funcdesc}{ungetch}{char}
+ Cause the character \var{char} to be ``pushed back'' into the
+ console buffer; it will be the next character read by
+ \function{getch()} or \function{getche()}.
+\end{funcdesc}
+
+
+\subsection{Other Functions \label{msvcrt-other}}
+
+\begin{funcdesc}{heapmin}{}
+ Force the \cfunction{malloc()} heap to clean itself up and return
+ unused blocks to the operating system. This only works on Windows
+ NT. On failure, this raises \exception{IOError}.
+\end{funcdesc}
