TEMPLATE_INSTANTIATION_DATA structure

::: moniker range="<=msvc-140"

The C++ Build Insights SDK is compatible with Visual Studio 2017 and later. To see the documentation for these versions, set the Visual Studio Version selector control for this article to Visual Studio 2017 or later. It's found at the top of the table of contents on this page.

The TEMPLATE_INSTANTIATION_DATA structure describes a template instantiation.

Syntax

typedef struct TEMPLATE_INSTANTIATION_DATA_TAG
{
    unsigned long long  SpecializationSymbolKey;
    unsigned long long  PrimaryTemplateSymbolKey;
    int                 KindCode;

} TEMPLATE_INSTANTIATION_DATA;

Members

Name	Description
SpecializationSymbolKey	The key for the template specialization's type. This value is unique within the trace being analyzed.
PrimaryTemplateSymbolKey	The key for the primary template type that was specialized. This value is unique within the trace being analyzed.
KindCode	The template instantiation's type. For more information, see TEMPLATE_INSTANTIATION_KIND_CODE.

Remarks

The keys in the TEMPLATE_INSTANTIATION_DATA structure are unique within the trace being analyzed. However, two different keys coming from different compiler front-end passes may point to two identical types. When consuming TEMPLATE_INSTANTIATION_DATA information from multiple compiler front-end passes, use the SYMBOL_NAME events to determine if two types are the same. SymbolName events are emitted at the end of a compiler front-end pass, after all template instantiations have taken place.
