- Replace '-present' with '-2020' (fixes #329) - Use correct format: Copyright (C) <year> <name of author> - Fix some obviously incorrect years from copy/paste i.e. avoid time travel

|
|
* Each hash must be wrapped in a thin redirector conformant with the BMK_benchfn_t.
|
|
* BMK_benchfn_t is generic, not specifically designed for hashes.
|
|
* For hashes, the following parameters are expected to be useless:
|
|
* dst, dstCapacity, customPayload.
|
|
*
|
|
* The result of each hash is assumed to be provided as function return value.
|
|
* This condition is important for latency measurements.
