From 4375cebc68d757238f3129f2472ec863dabc526b Mon Sep 17 00:00:00 2001 From: Tim Foley Date: Wed, 14 Oct 2020 13:55:45 -0700 Subject: Add reflection API access to global params type layout (#1577) This change adds a single new entry point to our reflection API that allows an application to query the `TypeLayout` that represents the global-scope shader parameters. This can be used by the application in order to detect when the global parameters have required allocation of a default constant buffer, or simply to unify the handling of the global scope with handling of other kinds of parameters. --- source/slang/slang-reflection.cpp | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'source') diff --git a/source/slang/slang-reflection.cpp b/source/slang/slang-reflection.cpp index 1daec501d..1b0a590cc 100644 --- a/source/slang/slang-reflection.cpp +++ b/source/slang/slang-reflection.cpp @@ -1560,3 +1560,12 @@ SLANG_API int spComputeStringHash(const char* chars, size_t count) { return (int)getStableHashCode32(chars, count); } + +SLANG_API SlangReflectionTypeLayout* spReflection_getGlobalParamsTypeLayout( + SlangReflection* reflection) +{ + auto programLayout = convert(reflection); + if(!programLayout) return nullptr; + + return convert(programLayout->parametersLayout->typeLayout); +} -- cgit v1.2.3
