IDiaStackWalkHelper: IUnknown
Methods in VTable Order
This table shows the methods of IDiaStackWalkHelper:
| Method | Description |
|---|---|
IDiaStackWalkHelper::get_registerValue |
Retrieves the value of a register. |
IDiaStackWalkHelper::put_registerValue |
Sets the value of a register. |
IDiaStackWalkHelper::readMemory |
Reads a block of data from the executable's image in memory. |
IDiaStackWalkHelper::searchForReturnAddress |
Searches the specified stack frame for the nearest function return address. |
IDiaStackWalkHelper::searchForReturnAddressStart |
Searches the specified stack frame for a return address at or near the specified stack address. |
IDiaStackWalkHelper::frameForVA |
Retrieves the stack frame that contains the specified virtual address (VA). |
IDiaStackWalkHelper::symbolForVA |
Retrieves the symbol that contains the specified VA. Note: Symbol must have the type SymTagFunctionType (a value from the SymTagEnum Enumeration enumeration). |
IDiaStackWalkHelper::pdataForVA |
Returns the PDATA data block associated with the specified VA. |
IDiaStackWalkHelper::imageForVA |
Retrieves the starting VA of an executable, given a VA somewhere in the executable's memory space. |
IDiaStackWalkHelper::addressForVA |
Returns the equivalent address (section and offset) for the specified VA. |
IDiaStackWalkHelper::numberOfFunctionFragmentsForVA |
Retrieves the number of discontiguous fragments for the function at the specified VA. |
IDiaStackWalkHelper::functionFragmentsForVA |
Retrieves the addresses and lengths of discontiguous fragments for the function at the specified VA. |
Remarks
This interface is called by the Debug Interface Access (DIA) code to obtain information about the executable to construct a list of stack frames during program execution.
Notes for Callers
A client application implements this interface to support walking the stack during program execution. An instance of this interface is passed to the IDiaStackWalker::getEnumFrames or IDiaStackWalker::getEnumFrames2 methods.
