Overview
Concrete tool for selecting the best available hardware backend provided by the GGML library.
Description
ggml_backend_init_best is a C function in the GGML tensor library that inspects the global backend registry, ranks every discovered device by computational capability (GPU > iGPU > CPU), and returns a ready-to-use backend handle pointing to the highest-ranked device. It abstracts away all hardware probing so that callers obtain an optimal backend with a single, zero-argument call. The function depends on ggml-backend.h and ggml-backend-impl.h for type definitions and registry internals.
Usage
Call this function at application startup, after ggml_backend_load_all() has populated the backend registry with all available plugins. The returned handle can then be passed to buffer-allocation and graph-computation routines. When the backend is no longer needed, release it with ggml_backend_free().

Usage Examples
#include "ggml-backend.h"
// Load all available backend plugins
