/**
* Fuzz target interface.
* Fuzz targets have some common parameters passed as macros during compilation.
* Check the documentation for each individual fuzzer for more parameters.
*
* @param STATEFUL_FUZZING:
* Define this to reuse state between fuzzer runs. This can be useful to
* test code paths which are only executed when contexts are reused.
* WARNING: Makes reproducing crashes much harder.
* Default: Not defined.
* @param FUZZ_RNG_SEED_SIZE:
* The number of bytes of the source to look at when constructing a seed
* for the deterministic RNG. These bytes are discarded before passing
* the data to zstd functions. Every fuzzer initializes the RNG exactly
* once before doing anything else, even if it is unused.
* Default: 4.
* @param ZSTD_DEBUG:
* This is a parameter for the zstd library. Defining `ZSTD_DEBUG=1`
* enables assert() statements in the zstd library. Higher levels enable
* logging, so aren't recommended. Defining `ZSTD_DEBUG=1` is
* recommended.
* @param MEM_FORCE_MEMORY_ACCESS:
* This flag controls how the zstd library accesses unaligned memory.
* It can be undefined, or 0 through 2. If it is undefined, it selects
* the method to use based on the compiler. If testing with UBSAN set
* MEM_FORCE_MEMORY_ACCESS=0 to use the standard compliant method.
* @param FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION
* This is the canonical flag to enable deterministic builds for fuzzing.
* Changes to zstd for fuzzing are gated behind this define.
* It is recommended to define this when building zstd for fuzzing.
