Similar to XLOG(...) except only log a message every

Synopsis

#define XLOG_EVERY_N_EXACT(level, n, …​)

The internal counter is process‐global and threadsafe and increments are atomic. The over‐logging and under‐logging schenarios of XLOG_EVERY_N(...) are avoided, traded off for the performance degradation of atomic‐rmw operations.

Parameters

invocations, exactly.
