Elements

SymTagNull
Indicates that the symbol has no type.

SymTagExe
Indicates that the symbol is an .exe file. There is only one SymTagExe symbol per symbol store. It serves as the global scope and does not have a lexical parent.

SymTagCompiland
Indicates the compiland symbol for each compiland component of the symbol store. For native applications, SymTagCompiland symbols correspond to the object files linked into the image. For some kinds of Microsoft Intermediate Language (MSIL) images, there is one compiland per class.

SymTagCompilandDetails
Indicates that the symbol contains extended attributes of the compiland. Retrieving these properties may require loading compiland symbols.

SymTagCompilandEnv
Indicates that the symbol is an environment string defined for the compiland.

SymTagFunction
Indicates that the symbol is a function.

SymTagBlock
Indicates that the symbol is a nested block.

SymTagData
Indicates that the symbol is data.

SymTagAnnotation
Indicates that the symbol is for a code annotation. Children of this symbol are constant data strings (SymTagData, LocIsConstant, DataIsConstant). Most clients ignore this symbol.

SymTagLabel
Indicates that the symbol is a label.

SymTagPublicSymbol
Indicates that the symbol is a public symbol. For native applications, this symbol is the COFF external symbol encountered while linking the image.

SymTagUDT
Indicates that the symbol is a user-defined type (structure, class, or union).

SymTagEnum
Indicates that the symbol is an enumeration.

SymTagFunctionType
Indicates that the symbol is a function signature type.

SymTagPointerType
Indicates that the symbol is a pointer type.

SymTagArrayType
Indicates that the symbol is an array type.

SymTagBaseType
Indicates that the symbol is a base type.

SymTagTypedef
Indicates that the symbol is a typedef, that is, an alias for another type.

SymTagBaseClass
Indicates that the symbol is a base class of a user-defined type.

SymTagFriend
Indicates that the symbol is a friend of a user-defined type.

SymTagFunctionArgType
Indicates that the symbol is a function argument.

SymTagFuncDebugStart
Indicates that the symbol is the end location of the function's prologue code.

SymTagFuncDebugEnd
Indicates that the symbol is the beginning location of the function's epilogue code.

SymTagUsingNamespace
Indicates that the symbol is a namespace name, active in the current scope.

SymTagVTableShape
Indicates that the symbol is a virtual table description.

SymTagVTable
Indicates that the symbol is a virtual table pointer.

SymTagCustom
Indicates that the symbol is a custom symbol and is not interpreted by DIA.

SymTagThunk
Indicates that the symbol is a thunk used for sharing data between 16 and 32 bit code.

SymTagCustomType
Indicates that the symbol is a custom compiler symbol.

SymTagManagedType
Indicates that the symbol is in metadata.

SymTagDimension
Indicates that the symbol is a FORTRAN multi-dimensional array.

SymTagCallSite
Indicates that the symbol represents the call site.

SymTagInlineSite
Indicates that the symbol represents the inline site.

SymTagBaseInterface
Indicates that the symbol is a base interface.

SymTagVectorType
Indicates that the symbol is a vector type.

SymTagMatrixType
Indicates that the symbol is a matrix type.

SymTagHLSLType
Indicates that the symbol is a High Level Shader Language type.

Remarks

All symbols within a debug file have an identifying tag that specifies the symbol's type.

The values in this enumeration are returned by a call to the IDiaSymbol::get_symTag method.

The values in this enumeration are passed to the following methods to limit the scope of the search to a specific symbol type:

• IDiaSession::findSymbolByAddr

• IDiaSession::findSymbolByRVA

• IDiaSession::findSymbolByRVAEx

• IDiaSession::findSymbolByToken

• IDiaSession::findSymbolByVA

• IDiaSession::findSymbolByVAEx

• IDiaSession::findChildren

• IDiaSymbol::findChildren
