ZDICT_trainFromBuffer_legacy(): Train a dictionary from an array of samples. Samples must be stored concatenated in a single flat buffer samplesBuffer, supplied with an array of sizes samplesSizes, providing the size of each sample, in order. The resulting dictionary will be saved into dictBuffer. parameters is optional and can be provided with values set to 0 to mean “default”. @return: size of dictionary stored into dictBuffer (<= dictBufferCapacity) or an error code, which can be tested with ZDICT_isError(). See ZDICT_trainFromBuffer() for details on failure modes. Tips: In general, a reasonable dictionary has a size of ~ 100 KB. It’s possible to select smaller or larger size, just by specifying dictBufferCapacity. In general, it’s recommended to provide a few thousands samples, though this can vary a lot. It’s recommended that total size of all samples be about ~x100 times the target size of dictionary. Note: ZDICT_trainFromBuffer_legacy() will send notifications into stderr if instructed to, using notificationLevel>0.
