C Interface

The C-interface provides access to the C++ classes through function calls. Because C does not have classes they are passed as opaque pointers, i.e. pointers to an incomplete type.

A proxy instance can be created by a call to one of the constructor functions:

• CPU_Optimized_create() from CPU/Optimized/OptimizedC.h to create an instance of idg::proxy::cpu::Optimized.

• CPU_Reference_create() from CPU/Reference/ReferenceC.h to create an instance of idg::proxy::cpu::Reference.

• CUDA_Generic_create() from CUDA/Generic/GenericC.h to create an instance of idg::proxy::cuda::Generic.

• CUDA_Unified_create() from CUDA/Unified/UnifiedC.h to create an instance of idg::proxy::cuda::Unified.

• HybridCUDA_GenericOptimized_create() from Hybrid/CUDA/GenericOptimized/GenericOptimized.h to create an instance of idg::proxy::hybrid::GenericOptimized.

• HybridCUDA_UnifiedOptimized_create() from Hybrid/CUDA/UnifiedOptimized/UnifiedOptimizedC.h to create an instance of idg::proxy::hybrid::UnifiedOptimized.

Afterwards the proxy need to be destroyed by a call to Proxy_destroy()

• ProxyC.h
• CPU/Reference/ReferenceC.h
• CPU/Optimized/OptimizedC.h
• CUDA/Generic/GenericC.h
• CUDA/Unified/UnifiedC.h
• Hybrid/CUDA/GenericOptimized/GenericOptimized.h
• Hybrid/CUDA/UnifiedOptimized/UnifiedOptimizedC.h
