+.Dt CK_HS_GROW 3
+.Sh NAME
+.Nm ck_hs_grow
+.Nd enlarge hash table capacity
+.Sh LIBRARY
+Concurrency Kit (libck, \-lck)
+.Sh SYNOPSIS
+.In ck_hs.h
+.Ft bool
+.Fn ck_hs_grow "ck_hs_t *hs" "unsigned long capacity"
+.Sh DESCRIPTION
+The
+.Fn ck_hs_grow 3
+function will resize the hash set in order to be
+able to store at least the number of entries specified by
+.Fa capacity
+at a load factor of one. The default hash set load factor
+is 0.5. If you wish to minimize the likelihood of memory allocations
+for a hash set meant to store n entries, then specify a
+.Fa capacity
+of 2n. The default behavior of ck_hs is to round
+.Fa capacity
+to the next power of two if it is not already a power of two.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn ck_hs_grow 3
+return true and otherwise returns a false on failure.
+.Sh ERRORS
+Behavior is undefined if
+.Fa hs
+is uninitialized. This function will only
+return false if there are internal memory allocation
+failures.
