ZDICT_trainFromBuffer() : 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. @return : size of dictionary stored into dictBuffer (<= dictBufferCapacity) or an error code, which can be tested with ZDICT_isError(). Tips : In general, a reasonable dictionary has a size of ~ 100 KB. It's obviously possible to target smaller or larger ones, just by specifying different dictBufferCapacity. In general, it's recommended to provide a few thousands samples, but this can vary a lot. It's recommended that total size of all samples be about ~x100 times the target size of dictionary.
