Function pointer declaration to free a mapping.

Parameters

  pMapping | mapping to be freed

typedef void(*) uno_getMappingFunc(struct _uno_Mapping **ppMapping, struct _uno_Environment *pFrom, struct _uno_Environment *pTo, rtl_uString *pAddPurpose)

Callback function pointer declaration to get a mapping.

Parameters

  ppMapping | inout mapping
  pFrom | source environment
  pTo | destination environment
  pAddPurpose | additional purpose

## ◆ uno_MapInterfaceFunc

typedef void(*) uno_MapInterfaceFunc(struct _uno_Mapping *pMapping, void **ppOut, void *pInterface, struct _typelib_InterfaceTypeDescription *pInterfaceTypeDescr)

Function pointer declaration to map an interface from one environment to another.

Parameters

  pMapping | mapping
  ppOut | [inout] destination interface; existing interfaces are released
  pInterface | source interface
  pInterfaceTypeDescr | type description of the interface

## ◆ uno_Mapping

This is the binary specification of a mapping.

## ◆ uno_ReleaseMappingFunc

typedef void(*) uno_ReleaseMappingFunc(struct _uno_Mapping *)

Function pointer declaration to release a UNO mapping.

## Function Documentation

## ◆ uno_getMapping()

CPPU_DLLPUBLIC void uno_getMapping | ( | struct _uno_Mapping ** | ppMapping,
|  | struct _uno_Environment * | pFrom,
|  | struct _uno_Environment * | pTo,
|  | rtl_uString * | pAddPurpose )

Gets an interface mapping from one environment to another.

Parameters

  ppMapping | [inout] mapping; existing mapping will be released
  pFrom | source environment
  pTo | destination environment (interfaces resulting in mapInterface() call can be used in this language environment)
  pAddPurpose | additional purpose of mapping (e.g., protocolling); defaults to 0 (none)

## ◆ uno_getMappingByName()

CPPU_DLLPUBLIC void uno_getMappingByName | ( | struct _uno_Mapping ** | ppMapping,
|  | rtl_uString * | pFrom,
|  | rtl_uString * | pTo,
|  | rtl_uString * | pAddPurpose )

Gets an interface mapping from one language environment to another by corresponding environment type names.

Parameters

  ppMapping | [inout] mapping; existing mapping will be released
  pFrom | source environment type name
  pTo | destination environment type name (interfaces resulting in mapInterface() call can be used in this language environment)
  pAddPurpose | additional purpose of mapping (e.g., protocolling); defaults to 0 (none)

## ◆ uno_registerMapping()
