.Dt CK_HT_ENTRY_EMPTY 3
.Sh NAME
.Nm ck_ht_entry_empty
.Nd determine whether entry contains a key-value pair
.Sh LIBRARY
Concurrency Kit (libck, \-lck)
.Sh SYNOPSIS
.In ck_ht.h
.Ft bool
.Fn ck_ht_entry_empty "ck_ht_entry_t *entry"
.Sh DESCRIPTION
The
.Fn ck_ht_entry_empty
function will return
.Dv false
if
.Fa entry
points to a valid key-value pair. If
.Fa entry
does not point to a valid key-value pair it
returns
.Dv true.
It is expected that the object pointed to by
.Fa entry
was initialized by a preceding call to the
.Xr ck_ht_entry_set
family of functions, the
.Xr ck_ht_get_spmc 3
function or the
.Xr ck_ht_set_spmc 3
function.
.Sh ERRORS
Behavior is undefined if
.Fa entry
has not been initialized.
