ISymUnmanagedWriter::OpenScope Method
Opens a new lexical scope in the current method. The scope becomes the new current scope and is pushed onto a stack of scopes. Scopes must form a hierarchy. Siblings are not allowed to overlap.
HRESULT OpenScope(
[in] ULONG32 startOffset,
[out, retval] ULONG32* pRetVal);
Parameters
- startOffset
[in] The offset of the first instruction in the lexical scope, in bytes, from the beginning of the method.
- pRetVal
[out] A pointer to a ULONG32 that receives the scope identifier.
Return Value
S_OK if the method succeeds; otherwise, E_FAIL or some other error code.
Requirements
Header: CorSym.idl
Remarks
ISymUnmanagedWriter::OpenScope Method returns an opaque scope identifier that can be used with ISymUnmanagedWriter::SetScopeRange Method to define a scope's starting and ending offset at a later time. In this case, the offsets passed to ISymUnmanagedWriter::OpenScope Method and ISymUnmanagedWriter::CloseScope Method are ignored. Scope identifiers are valid only in the current method.
