IDebugControl::OutputDisassembly method (dbgeng.h)
The OutputDisassembly method disassembles a processor instruction and sends the disassembly to the output callbacks.
Syntax
HRESULT OutputDisassembly(
[in] ULONG OutputControl,
[in] ULONG64 Offset,
[in] ULONG Flags,
[out] PULONG64 EndOffset
);
Parameters
[in] OutputControl
Specifies the output control that determines which client's output callbacks receive the output. For possible values, see DEBUG_OUTCTL_XXX. For more information about output, see Input and Output.
[in] Offset
Specifies the location in the target's memory of the instruction to disassemble.
[in] Flags
Specifies the bit-flags that affect the behavior of this method. The following table lists the bits that can be set.
| Bit-Flag | Effect when set |
|---|---|
| DEBUG_DISASM_EFFECTIVE_ADDRESS | Compute the effective address from the current register information and display it. |
| DEBUG_DISASM_MATCHING_SYMBOLS | If the address of the instruction has an exact symbol match, output the symbol. |
| DEBUG_DISASM_SOURCE_LINE_NUMBER | Include the source line number of the instruction in the output. |
| DEBUG_DISASM_SOURCE_FILE_NAME | Include the source file name in the output. |
[out] EndOffset
Receives the location in the target's memory of the instruction that follows the disassembled instruction.
Return value
This method can also return error values. See Return Values for more details.
| Return code | Description |
|---|---|
|
The method was successful. |
Remarks
The assembly language depends on the effective processor type of the target system. For information about the assembly language, see the processor documentation.
