CK_HT_SET_SPMC(3)     DragonFly Library Functions Manual     CK_HT_SET_SPMC(3)


NAME

     ck_ht_set_spmc - store key-value pair into hash table


LIBRARY

     Concurrency Kit (libck, -lck)


SYNOPSIS

     #include <ck_ht.h>

     bool
     ck_ht_set_spmc(ck_ht_t *ht, ck_ht_hash_t h, ck_ht_entry_t *entry);


DESCRIPTION

     The ck_ht_set_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
     initialized 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_entry_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_set_spmc() was successful then the key-value pair in
     entry will contain the previous key-value pair associated with the key
     originally contained in the entry argument. If the operation was
     unsuccessful then entry is unmodified.

     This function is safe to call in the presence of concurrent
     ck_ht_get_spmc operations.


RETURN VALUES

     Upon successful completion ck_ht_set_spmc() returns true and otherwise
     returns 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
     attempting to grow.
