Debugging Tools for Windows


The SetPseudoValues method sets the value of several pseudo-registers.

    IN ULONG  Source,
    IN ULONG  Count,
    IN ULONG  Start,


Specifies the register source to query.

The possible values are listed in the following table.

Value Register source
DEBUG_REGSRC_DEBUGGEE Fetch register information from the target.
DEBUG_REGSRC_EXPLICIT Fetch register information from the current explicit register context.
DEBUG_REGSRC_FRAME Fetch register information from the current scope's register context.

Note Stack unwinding does not guarantee accurate updating of the register context, so the scope frame's register context might not be accurate in all cases.

Specifies the number of pseudo-registers whose values are being set.
Specifies an array of indices of pseudo-registers. These are the pseudo-registers whose values will be set. The size of Indices is Count. If Indices is NULL, Start is used to specify the indices instead.
Specifies the index of the first pseudo-register whose value will be set. The pseudo-registers with indices between Start and Start plus Count minus one, will be set. Start is only used if Indices is NULL.
Specifies the new values of the pseudo-registers. The number of elements this array holds is Count. See DEBUG_VALUE for a description of this parameter type.

Return Value

The method was successful.

This list does not contain all the errors that might occur. For a list of possible errors, see HRESULT Values.

Interface Version

SetPseudoValues is available in IDebugRegisters2 and later versions.
