#ifndef TRT_SAMPLE_ENTRYPOINTS_H
#define TRT_SAMPLE_ENTRYPOINTS_H

//! \file sampleEntrypoints.h
//!
//! Declares and conditionally defines entrypoints needed to create base TensorRT objects, depending
//! on whether the given sample uses TRT at link time or dynamically.  Since common code is built once
//! and shared across all samples (both link-time and dynamic TRT), it does not define these entrypoints,
//! so each sample must define them individually.
//!
//! Samples that use TRT at link time can define DEFINE_TRT_ENTRYPOINTS before including this header to
//! pick up the definitions here.
