<h1>Mono Internals</h1>

	<p>This section documents some of the internal APIs used
	inside Mono that developers extending or altering Mono might
	want to use.

<h2>Strings</h2>

<h3>Other Encodings</h3>

	<p>These routines are used when coping with strings that come
	from Mono's environment, and might be encoded in one or more
	of the external encodings.

	<p>For example, some file systems might historically contain a
	mix of file names with both old and new encodings, typically
	UTF8 for new files, and the old files would be encoded in an 8
	bit character set (ISO-8859-1 for example).
	
	<p>These routines try a number of encodings, those specified
	in the <tt>MONO_ENCODINGS</tt> environment variable and return
	unicode strings that can be used internally.

	<p>See the mono(1) man page for more details.

<h2>Metadata Loader Locking: Internals</h2>

	<p>The locking functions here are used by code in class.c and
	metadata.c to lock access to the shared hashtables inside the
	MonoImage.
