Describes a function table for any version of the Resource API.

Syntax

typedef struct CLRES_FUNCTION_TABLE {
  DWORD TableSize;
  DWORD Version;
  union {
    CLRES_V1_FUNCTIONS V1Functions;
    CLRES_V2_FUNCTIONS V2Functions;
    CLRES_V3_FUNCTIONS V3Functions;
    CLRES_V4_FUNCTIONS V4Functions;
  } DUMMYUNIONNAME;
} CLRES_FUNCTION_TABLE, *PCLRES_FUNCTION_TABLE;

Members

TableSize

Count of bytes in the structure.

This can contain one of these values:

CLRES_V1_FUNCTION_SIZE

The size of the function table for Resource API version 1.0.

CLRES_V2_FUNCTION_SIZE

The size of the function table for Resource API version 2.0.

Windows Server 2008 R2: This value is not supported before Windows Server 2012.

CLRES_V3_FUNCTION_SIZE

The size of the function table for Resource API version 3.0.

Windows Server 2008 R2 and Windows Server 2012: This value is not supported before Windows Server 2012 R2.

Version

The supported version of the Resource API.

This can contain one of these values:

CLRES_VERSION_V1_00 (0x100)

Resource API version 1.0.

CLRES_VERSION_V2_00 (0x200)

Resource API version 2.0.

Windows Server 2008 R2: This value is not supported before Windows Server 2012.

CLRES_VERSION_V3_00 (0x300)

Resource API version 3.0.

Windows Server 2008 R2 and Windows Server 2012: This value is not supported before Windows Server 2012 R2.

DUMMYUNIONNAME

DUMMYUNIONNAME.V1Functions

A CLRES_V1_FUNCTIONS structure that contains the table of entry points included in the Resource API version 1.0.

DUMMYUNIONNAME.V2Functions

A CLRES_V2_FUNCTIONS structure that contains the table of entry points included in the Resource API version 2.0.

Windows Server 2008 R2: This member was added in Windows Server 2012.

DUMMYUNIONNAME.V3Functions

A CLRES_V3_FUNCTIONS structure that contains the table of entry points included in the Resource API version 3.0.

Windows Server 2008 R2 and Windows Server 2012: This member was added in Windows Server 2012 R2.

DUMMYUNIONNAME.V4Functions

Remarks

Only the first two members are guaranteed to be at the same offset within the CLRES_FUNCTION_TABLE structure. All other entries within this structure are dependent on the Resource API version supported.

The V1Functions member is a CLRES_V1_FUNCTIONS structure containing pointers to all Resource API entry points except Startup. All pointers must be non-NULL except for pointers to the following entry point functions:

To create a function table for version 1.0 of the Resource API, use the CLRES_V1_FUNCTION_TABLE macro.
