Further information
This function computes a hash value for a given data buffer, it can be used for implementing the
XPRM_CPY_HASH option of the module type function
copy (See section
Table of types). The provided initial value
hv can be used to combine a list of buffers by using the returned value of a previous call as input for the following.
