The key specified in +.Fa entry +is expected to have the hash value specified by the +.Fa h +argument. +.Pp +If +.Fa ht +was created with CK_HT_MODE_BYTESTRING then +.Fa entry +must have been initialized with the +.Xr ck_ht_entry_set 3 +function. If +.Fa ht +was created with CK_HT_MODE_DIRECT then +.Fa entry +must have been initialized with the +.Xr ck_ht_entry_set_direct 3 +function. +.Pp +It is expected that +.Fa h +was initialized with +.Xr ck_ht_hash 3 +if +.Fa ht +was created with CK_HT_MODE_BYTESTRING. If +.Fa ht +was initialized with CK_HT_MODE_DIRECT then it is +expected that +.Fa h +was initialized with the +.Xr ck_ht_hash_direct 3 +function. +.Pp +If the call to +.Fn ck_ht_set_spmc +was successful then the key-value pair in +.Fa entry +will contain the previous key-value pair associated +with the key originally contained in the +.Fa entry +argument. If the operation was unsuccessful then +.Fa entry +is unmodified. +.Pp +This function is safe to call in the presence of concurrent +.Xr ck_ht_get_spmc +operations. +.Sh RETURN VALUES +Upon successful completion +.Fn ck_ht_set_spmc +returns +.Dv true +and otherwise returns +.Dv false +on failure. +.Sh ERRORS +.Bl -tag -width Er +Behavior is undefined if +.Fa entry +or +.Fa ht +are uninitialized. The function will return +.Dv false +if the hash table required to be grown but failed +while attempting to grow. +.El +.Sh SEE ALSO +.Xr ck_ht_stat 3 , +.Xr ck_ht_init 3 , +.Xr ck_ht_destroy 3 , +.Xr ck_ht_hash 3 , +.Xr ck_ht_hash_direct 3 , +.Xr ck_ht_put_spmc 3 , +.Xr ck_ht_gc 3 , +.Xr ck_ht_get_spmc 3 , +.Xr ck_ht_grow_spmc 3 , +.Xr ck_ht_remove_spmc 3 , +.Xr ck_ht_reset_spmc 3 , +.Xr ck_ht_reset_size_spmc 3 , +.Xr ck_ht_count 3 , +.Xr ck_ht_entry_empty 3 , +.Xr ck_ht_entry_key_set 3 , +.Xr ck_ht_entry_key_set_direct 3 , +.Xr ck_ht_entry_key 3 , +.Xr ck_ht_entry_key_length 3 , +.Xr ck_ht_entry_value 3 , +.Xr ck_ht_entry_set 3 , +.Xr ck_ht_entry_set_direct 3 , +.Xr ck_ht_entry_key_direct 3 , +.Xr ck_ht_entry_value_direct 3 , +.Xr ck_ht_iterator_init 3 , +.Xr ck_ht_next 3 +.Pp +Additional information available at http://concurrencykit.org/ -- cgit v1.2.3
