Variable Documentation

◆ cs_main

RecursiveMutex cs_main

Mutex to guard access to validation specific variables, such as reading or changing the chainstate.

This may also need to be locked when updating the transaction pool, e.g. on AcceptToMemoryPool. See CTxMemPool::cs comment for details.

The transaction pool has a separate lock to allow reading from it and the chainstate at the same time.

Definition at line 138 of file validation.cpp.

◆ NUM_GETBLOCKSTATS_PERCENTILES

constexpr int NUM_GETBLOCKSTATS_PERCENTILES = 5
staticconstexpr
