Usage

#include <ck_hs.h>

void

ck_hs_stat(ck_hs_t *hs, struct ck_hs_stat *st);

Library

Concurrency Kit (libck, -lck)

Overview

The ck_hs_stat(3) function will store various hash set statistics in the object pointed to by st. The ck_hs_stat structure is defined as follows:

struct ck_hs_stat {
	unsigned long tombstones;   /* Current number of tombstones in hash set. */
	unsigned long n_entries;    /* Current number of keys in hash set. */
	unsigned int probe_maximum; /* Longest read-side probe sequence. */
};

Return values

ck_hs_stat(3) has no return value.

Errors

Behavior is undefined if hs is uninitialized. Behavior is undefined if this function is called by a non-writer thread.
