# ck\_rhs\_stat(3)

get hash set status

## NAME

**ck\_rhs\_stat** – get hash set status

## LIBRARY

Concurrency Kit (libck, -lck)

## SYNOPSIS

**#include \<ck\_rhs.h\>**

*void*\

**ck\_rhs\_stat**(*ck\_rhs\_t \*hs*, *struct ck\_rhs\_stat \*st*);

## DESCRIPTION

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

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

## RETURN VALUES

**ck\_rhs\_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.
