ISymUnmanagedWriter::DefineLocalVariable Method

  • Article

Defines a single variable in the current lexical scope. This method can be called multiple times for a variable of the same name that has multiple homes throughout a scope. In this case, however, the values of the startOffset and endOffset parameters must not overlap.

Syntax

HRESULT DefineLocalVariable(  
    [in] const WCHAR  *name,  
    [in] ULONG32      attributes,  
    [in] ULONG32      cSig,  
    [in, size_is(cSig)] unsigned char signature[],  
    [in] ULONG32      addrKind,  
    [in] ULONG32      addr1,  
    [in] ULONG32      addr2,  
    [in] ULONG32      addr3,  
    [in] ULONG32      startOffset,  
    [in] ULONG32      endOffset);

Parameters

name
[in] A pointer to a WCHAR that defines the local variable name.

attributes
[in] The local variable attributes.

cSig
[in] A ULONG32 that indicates the size, in bytes, of the signature buffer.

signature
[in] The local variable signature.

addrKind
[in] The address type.

addr1
[in] The first address for the parameter specification.

addr2
[in] The second address for the parameter specification.

addr3
[in] The third address for the parameter specification.

startOffset
[in] The start offset for the variable. This parameter is optional. If it is 0, this parameter is ignored and the variable is defined throughout the entire scope. If it is a nonzero value, the variable falls within the offsets of the current scope.

endOffset
[in] The end offset for the variable. This parameter is optional. If it is 0, this parameter is ignored and the variable is defined throughout the entire scope. If it is a nonzero value, the variable falls within the offsets of the current scope.

Return Value

S_OK if the method succeeds; otherwise, E_FAIL or some other error code.
