.Dt CK_HT_GROW_SPMC 3
.Sh NAME
.Nm ck_ht_grow_spmc
.Nd resize a hash table if necessary
.Sh LIBRARY
Concurrency Kit (libck, \-lck)
.Sh SYNOPSIS
.In ck_ht.h
.Ft bool
.Fn ck_ht_grow_spmc "ck_ht_t *ht" "uint64_t capacity"
.Sh DESCRIPTION
The
.Fn ck_ht_grow_spmc
function will resize the hash table in order to be able to
at least store the number of entries specified by
.Fa capacity
at a load factor of one. The default load hash table load factor is
0.5. If you wish to minimize the likelihood of memory allocations
for a hash table meant to store n entries then specify a capacity
of 2n. The default behavior of ck_ht is to round
.Fa capacity
to the next available power of two if it is not already a power
of two.
.Pp
This function is safe to call in the presence of concurrent
.Xr ck_ht_get_spmc 3
operations.
.Sh RETURN VALUES
Upon successful completion
.Fn ck_ht_grow_spmc
returns
.Dv true
and otherwise returns a
.Dv false
value.
.Sh ERRORS
.Bl -tag -width Er
Behavior is undefined if
.Fa ht
is uninitialized. The function will only return
.Dv false
if there are internal memory allocation failures.
