Debugging Tools for Windows


The OutputRegisters2 method formats and outputs the target's registers.

    IN ULONG  OutputControl,
    IN ULONG  Source,
    IN ULONG  Flags


Specifies which clients should be sent the output of the formatted registers. See DEBUG_OUTCTL_XXX for possible values.
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 which register sets to print. This can either be DEBUG_REGISTERS_DEFAULT to print commonly used registers, DEBUG_REGISTERS_ALL to print all of the register sets, or a combination of the values listed in the following table.
Value Description
DEBUG_REGISTERS_INT32 Print the 32-bit register set.
DEBUG_REGISTERS_INT64 Print the 64-bit register set.
DEBUG_REGISTERS_FLOAT Print the floating-point register set.

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

OutputRegisters2 is available in IDebugRegisters2 and later versions.


The registers are formatted in a way that is specific to the target architecture's register set.

The method OutputRegisters performs the same task as this method but always uses the target as the register source.

For an overview of the IDebugRegisters interface and other register-related methods, see Registers.
