IDebugSymbols3::GetNearNameByOffsetWide method (dbgeng.h)

  • Article

The GetNearNameByOffsetWide method returns the name of a symbol that is located near the specified location.

Syntax

HRESULT GetNearNameByOffsetWide(
  [in]            ULONG64  Offset,
  [in]            LONG     Delta,
  [out, optional] PWSTR    NameBuffer,
  [in]            ULONG    NameBufferSize,
  [out, optional] PULONG   NameSize,
  [out, optional] PULONG64 Displacement
);

Parameters

[in] Offset

Specifies the location in the target's virtual address space of the symbol from which the desired symbol is determined.

[in] Delta

Specifies the relationship between the desired symbol and the symbol located at Offset. If positive, the engine will return the symbol that is Delta symbols after the symbol located at Offset. If negative, the engine will return the symbol that is Delta symbols before the symbol located at Offset.

[out, optional] NameBuffer

Receives the symbol's name. The name is qualified by the module to which the symbol belongs (for example, mymodule!main). If NameBuffer is NULL, this information is not returned.

[in] NameBufferSize

Specifies the size in characters of the buffer NameBuffer. This size includes the space for the '\0' terminating character.

[out, optional] NameSize

Receives the size in characters of the symbol's name. This size includes the space for the '\0' terminating character. If NameSize is NULL, this information is not returned.

[out, optional] Displacement

Receives the difference between the value of Offset and the location in the target's memory address space of the symbol. If Displacement is NULL, this information is not returned.

Return value

This method may also return other error values. See Return Values for more details.

Return code Description
S_OK
 The method was successful.
S_FALSE
 The method was successful. However, the buffer was not large enough to hold the symbol's name so it was truncated.
E_NOINTERFACE
 No symbol matching the specifications of Offset and Delta was found.

Remarks

By increasing or decreasing the value of Delta, these methods can be used to iterate over the target's symbols starting at a particular location.

If Delta is zero, these methods behave the same way as GetNameByOffset.
