DebugExtensionQueryValueNames

The DebugExtensionQueryValueNames callback function recovers pseudo-register values.

HRESULT CALLBACK
  DebugExtensionQueryValueNames (
    __in PDEBUG_CLIENT  Client,
    __in ULONG  Flags,
    __out_ecount(BufferChars) PWSTR  Buffer,
    __in ULONG  BufferChars,
    __out PULONG  BufferNeeded
    );

Client: A client to use if the extension needs DbgEng functions.
Flags: Provides behavioral flags. This parameter is currently reserved.
Buffer: A string buffer that the caller provides, to be filled with the set of value names that the client wants to expose.
BufferChars: The count of wide characters in Buffer.
BufferNeeded: The number of wide characters that this function needs to complete successfully.

Return Value

DebugExtensionQueryValueNames might return one of the following values:

S_OK: The function was successfully completed.
S_FALSE: The function completed without error, but it obtained only partial results.

This function might also return error values. For more information about possible return values, see Return Values.

Comments

Value names must start with $$ and have a terminating NULL character. The Buffer string must also be NULL-terminated. For example, Buffer could be “$$myval1\0$$myval2\0\0”.

Requirements

Headers: The Dbgeng.h header file has the definitions of the callback prototypes.
