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.

Returns the size of the 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.
