both values are optional, select `0` if unknown.
`srcSize` can be unknown, in which case use ZSTD_CONTENTSIZE_UNKNOWN.
`dictSize` must be `0` when there is no dictionary.
cPar can be invalid : all parameters will be clamped within valid range in the @return struct.
This function never fails (wide contract)
