IDebugControl3::Disassemble method (dbgeng.h)
The Disassemble method disassembles a processor instruction in the target's memory.
Syntax
HRESULT Disassemble(
[in] ULONG64 Offset,
[in] ULONG Flags,
[out, optional] PSTR Buffer,
[in] ULONG BufferSize,
[out, optional] PULONG DisassemblySize,
[out] PULONG64 EndOffset
);
Parameters
[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. Currently the only flag that can be set is DEBUG_DISASM_EFFECTIVE_ADDRESS; when set, the engine will compute the effective address from the current register information and display it.
[out, optional] Buffer
Receives the disassembled instruction. If Buffer is NULL, this information is not returned.
[in] BufferSize
Specifies the size, in characters, of the Buffer buffer.
[out, optional] DisassemblySize
Receives the size, in characters, of the disassembled instruction. If DisassemblySize is NULL, this information is not returned.
[out] EndOffset
Receives the location in the target's memory of the instruction following 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. |
|
The method was successful. However, Buffer was too small to hold the disassembled instruction and the instruction was truncated to fit. |
Remarks
The assembly language depends on the effective processor type of the target system. For information about the assembly language, see the processor documentation.
The disassembly options--returned by GetAssemblyOptions--affect the operation of this method.
