Function Documentation

psi_report_cache_shutdown()

void psi_report_cache_shutdown

(

After the cache is de-initialized 'current_count' must be zero; otherwise we have allocated data that has not been deallocated (or has not been reported as deallocated).

psi_report_mem_alloc()

int psi_report_mem_alloc

(

size_t

size

)

Reports to PSI the allocation of 'size' bytes of data.

psi_report_mem_free()

void psi_report_mem_free	(	size_t	size,
		int	is_instrumented
	)

Reports to PSI the deallocation of 'size' bytes of data.

register_gcs_mutex_cond_psi_keys()

void register_gcs_mutex_cond_psi_keys
