IDebugSymbolGroup2::AddSymbolWide method (dbgeng.h)

Article

The AddSymbolWide method adds a symbol to a symbol group.

Syntax

HRESULT AddSymbolWide(
  [in]      PCWSTR Name,
  [in, out] PULONG Index
);

Parameters

[in] Name

The symbol's name. Name is examined as an expression to determine the symbol's type. This expression can include pointer, array, and structure dereferencing (for example, *my_pointer, my_array[1], or my_struct.some_field).

[in, out] Index

The index of the entry in the symbol group. When you are calling AddSymbol or AddSymbolWide, Index should point to the index of the symbol that you want. Or, if Index points to DEBUG_ANY_ID, the symbol is appended to the end of the list.

When this method returns, Index points to the actual index of the symbol. The index of a symbol is an identification number. The index ranges from zero through the number of symbols in the symbol group minus one.

Return value

Return code	Description
S_OK	The method was successful.

This method can also return error values. For more information, see Return Values.

Remarks

The symbol name in Name is evaluated by the C++ expression evaluator and can contain any C++ expression (for example, x+y).

If the index that you want is less than the size of the symbol group, the new symbol is added at the desired index. If the desired index is larger than the size of the symbol group, the new symbol is added to the end of the list (as in the case of DEBUG_ANY_ID).

For more information about symbol groups, see Scopes and Symbol Groups.
