.In ck_rhs.h
.Ft bool
.Fn ck_rhs_reset_size "ck_rhs_t *hs" "unsigned long size"
.Sh DESCRIPTION
The
.Fn ck_rhs_reset_size 3
function will remove all keys stored in the hash
set pointed to by the
.Fa hs
argument and create a new generation of the hash set that
is preallocated for
.Fa size
entries.
.Sh RETURN VALUES
If successful,
.Fn ck_rhs_reset_size 3
will return true and will otherwise return false on failure. This
function will only fail if a replacement hash set could not be
allocated internally.
.Sh ERRORS

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