	)

Process an incoming block.

This only returns after the best known valid block is made active. Note that it does not, however, guarantee that the specific block passed to it has been checked for validity!

If you want to possibly get feedback on whether pblock is valid, you must install a CValidationInterface (see validationinterface.h) - this will have its BlockChecked method called whenever any block completes validation.

Note that we guarantee that either the proof-of-work is valid on pblock, or (and possibly also) BlockChecked will have been called.

Call without cs_main held.

Parameters

[in]	pblock	The block we want to process.
[in]	fForceProcessing	Process this block even if unrequested; used for non-network block sources and whitelisted peers.
[out]	fNewBlock	A boolean which is set to indicate if the block was first received via this call

Returns: True if state.IsValid()
