virtual HandleType_t SourceMod::IHandleSys::CreateType	(	const char *	name,
		IHandleTypeDispatch *	dispatch,
		HandleType_t	parent,
		const TypeAccess *	typeAccess,
		const HandleAccess *	hndlAccess,
		IdentityToken_t *	ident,
		HandleError *	err
	)			`[pure virtual]`

Creates a new Handle type. NOTE: Currently, a child type may not have its own children. NOTE: Handle names must be unique if not private.

Parameters:

	name	Name of handle type (NULL or "" to be anonymous)
	dispatch	Pointer to a valid IHandleTypeDispatch object.
	parent	Parent handle to inherit from, 0 for none.
	typeAccess	Pointer to a TypeAccess object, NULL to use default or inherited permissions. Pointer can be temporary.
	hndlAccess	Pointer to a HandleAccess object to define default default permissions on each Handle. NULL to use default permissions.
	ident	Security token for any permissions. If typeAccess is NULL, this becomes the owning identity.
	err	Optional pointer to store an error code on failure (undefined on success).

Returns:: A new HandleType_t unique ID, or 0 on failure.

virtual bool SourceMod::IHandleSys::RemoveType	(	HandleType_t	type,
		IdentityToken_t *	ident
	)			`[pure virtual]`

Removes a handle type. NOTE: This removes all child types.

Parameters:

	type	Type chain to remove.
	ident	Identity token. Removal fails if the token does not match.

Returns:: True on success, false on failure.

virtual bool SourceMod::IHandleSys::FindHandleType	(	const char *	name,
		HandleType_t *	type
	)			`[pure virtual]`

Finds a handle type by name.

Parameters:

	name	Name of handle type to find (anonymous not allowed).
	type	Address to store found handle in (if not found, undefined).

Returns:: True if found, false otherwise.

virtual Handle_t SourceMod::IHandleSys::CreateHandle	(	HandleType_t	type,
		void *	object,
		IdentityToken_t *	owner,
		IdentityToken_t *	ident,
		HandleError *	err
	)			`[pure virtual]`

Creates a new handle.

Parameters:

	type	Type to use on the handle.
	object	Object to bind to the handle.
	owner	Owner of the new Handle (may be NULL).
	ident	Identity for type access if needed (may be NULL).
	err	Optional pointer to store an error code on failure (undefined on success).

Returns:: A new Handle_t, or 0 on failure.

virtual HandleError SourceMod::IHandleSys::FreeHandle	(	Handle_t	handle,
		const HandleSecurity *	pSecurity
	)			`[pure virtual]`

Frees the memory associated with a handle and calls any destructors. NOTE: This function will decrement the internal reference counter. It will only perform any further action if the counter hits 0.

Parameters:

	handle	Handle_t identifier to destroy.
	pSecurity	Security information struct (may be NULL).

Returns:: A HandleError error code.

virtual HandleError SourceMod::IHandleSys::CloneHandle	(	Handle_t	handle,
		Handle_t *	newhandle,
		IdentityToken_t *	newOwner,
		const HandleSecurity *	pSecurity
	)			`[pure virtual]`

Clones a handle by adding to its internal reference count. Its data, type, and security permissions remain the same.

Parameters:

	handle	Handle to duplicate. Any non-free handle target is valid.
	newhandle	Stores the duplicated handle in the pointer (must not be NULL).
	newOwner	New owner of cloned handle.
	pSecurity	Security information struct (may be NULL).

Returns:: A HandleError error code.

virtual HandleError SourceMod::IHandleSys::ReadHandle	(	Handle_t	handle,
		HandleType_t	type,
		const HandleSecurity *	pSecurity,
		void **	object
	)			`[pure virtual]`

Retrieves the contents of a handle.

Parameters:

	handle	Handle_t from which to retrieve contents.
	type	Expected type to read as. 0 ignores typing rules.
	pSecurity	Security information struct (may be NULL).
	object	Optional address to store object in.

Returns:: HandleError error code.

virtual bool SourceMod::IHandleSys::InitAccessDefaults	(	TypeAccess *	pTypeAccess,
		HandleAccess *	pHandleAccess
	)			`[pure virtual]`

Sets access permissions on one or more structures.

Parameters:

	pTypeAccess	Optional TypeAccess buffer to initialize with the default values.
	pHandleAccess	Optional HandleAccess buffer to initialize with the default values.

Returns:: True on success, false if version is unsupported.

virtual Handle_t SourceMod::IHandleSys::CreateHandleEx	(	HandleType_t	type,
		void *	object,
		const HandleSecurity *	pSec,
		const HandleAccess *	pAccess,
		HandleError *	err
	)			`[pure virtual]`

Creates a new handle.

Parameters:

	type	Type to use on the handle.
	object	Object to bind to the handle.
	pSec	Security pointer; pOwner is written as the owner, pIdent is used as the parent identity for authorization.
	pAccess	Access right descriptor for the Handle; NULL for type defaults.
	err	Optional pointer to store an error code on failure (undefined on success).

Returns:: A new Handle_t, or 0 on failure.
