	+; annotations:
	+; SAL 2.0 annotations are used to specify how system calls treat
	+; arguments that are passed using pointers. There are three basic
	+; annotations.
	+;
	+; _In_ Object pointed to will be read and not modified.
	+; _Out_ Object pointed to will be written and not read.
	+; _Inout_ Object pointed to will be written and read.
	+;
	+; These annotations are used alone when the pointer refers to a single
	+; object i.e. scalar types, structs, and pointers, and not NULL. Adding
	+; the _opt_ suffix, e.g. _In_opt_, implies that the pointer may also
	+; refer to NULL.
	+;
	+; For pointers to arrays, additional suffixes are added:
	;
	+; _In_z_, _Out_z_, _Inout_z_:
	+; for a NUL terminated array e.g. a string.
	+; _In_reads_z_(n),_Out_writes_z_(n), _Inout_updates_z_(n):
	+; for a NUL terminated array e.g. a string, of known length n bytes.
	+; _In_reads_(n),_Out_writes_(n),_Inout_updates_(n):
	+; for an array of n elements.
	+; _In_reads_bytes_(n), _Out_writes_bytes_(n), _Inout_updates_bytes(n):
	+; for a buffer of n-bytes.
