NAME ck_ht_put_spmc -- store unique key-value pair into hash table LIBRARY Concurrency Kit (libck, -lck) SYNOPSIS #include <ck_ht.h> bool ck_ht_put_spmc(ck_ht_t *ht, ck_ht_hash_t h, ck_ht_entry_t *entry); DESCRIPTION The ck_ht_put_spmc() function will store the key-value pair specified in the entry argument in the hash table pointed to by the ht argument. The key specified in entry is expected to have the hash value specified by the h argument. If ht was created with CK_HT_MODE_BYTESTRING then entry must have been ini- tialized with the ck_ht_entry_set(3) function. If ht was created with CK_HT_MODE_DIRECT then entry must have been initialized with the ck_ht_en- try_set_direct(3) function. It is expected that h was initialized with ck_ht_hash(3) if ht was created with CK_HT_MODE_BYTESTRING. If ht was initialized with CK_HT_MODE_DIRECT then it is expected that h was initialized with the ck_ht_hash_direct(3) function. If the call to ck_ht_put_spmc() was successful then the key-value pair in entry was successfully stored in the hash table pointed to by ht and will fail if the key specified in entry already exists with-in the hash table. Replacement semantics are provided by the ck_ht_set_spmc(3) function. This function is safe to call in the presence of concurrent ck_ht_get_spmc(3) operations. RETURN VALUES Upon successful completion ck_ht_put_spmc() returns true and otherwise re- turns false on failure. ERRORS Behavior is undefined if entry or ht are uninitialized. The function will return false if the hash table required to be grown but failed while at- tempting to grow or if the key specified in entry was already present in the hash table.
