Detailed Description

The file contains description of public component manager handles and interfaces for initialization and dynamic linking of VM components.

Classes
struct	_OpenInterface
	The _OpenInterface structure represents a virtual table of interface functions. More...
struct	_OpenComponent
	Default component interface. More...
struct	_OpenInstance
	The generic component instance. More...
struct	_OpenInstanceAllocator
	The private component interface used by a component manager to allocate and dispose instances. More...
struct	_OpenComponentManager
	The virtual table which contains public component manager interface. More...
Typedefs
Handles
Handles are opaque for an interface user. The user operates with handles by means of interface functions.
typedef _OpenInterface *	OpenInterfaceHandle
	The handle of the abstract component interface.
typedef _OpenComponent *	OpenComponentHandle
	The handle of the open component.
typedef _OpenInstance *	OpenInstanceHandle
	The handle of the open instance.
typedef _OpenInstanceAllocator *	OpenInstanceAllocatorHandle
	The handle of the instance allocator interface.
typedef _OpenComponentManager *	OpenComponentManagerHandle
	The handle of the component manager interface.
typedef int(*)	OpenComponentInitializer (OpenComponentHandle *p_component, OpenInstanceAllocatorHandle *p_allocator, apr_pool_t *pool)
	The generic component initialization function type.

Typedef Documentation

typedef struct _OpenInterface* OpenInterfaceHandle

The handle of the abstract component interface.

typedef struct _OpenComponent* OpenComponentHandle

The handle of the open component.

typedef struct _OpenInstance* OpenInstanceHandle

The handle of the open instance.

typedef struct _OpenInstanceAllocator* OpenInstanceAllocatorHandle

The handle of the instance allocator interface.

typedef struct _OpenComponentManager* OpenComponentManagerHandle

The handle of the component manager interface.

typedef int(*) OpenComponentInitializer(OpenComponentHandle *p_component, OpenInstanceAllocatorHandle *p_allocator, apr_pool_t *pool)

The generic component initialization function type.

Parameters:

[out]	p_component	on return, points to a handle of a default component interface
[out]	p_allocator	on return, points to a handle of a private instance allocation interface
	pool	a memory pool with the component lifetime

Returns:

APR_SUCCESS if successful, otherwise a non-zero error code
