CK_HS_SET(3)             BSD Library Functions Manual             CK_HS_SET(3)

     ck_hs_set -- store key into a hash set

     Concurrency Kit (libck, -lck)

     #include <ck_hs.h>

     ck_hs_set(ck_hs_t *hs, unsigned long hash, const void *key,
         void **previous);

     The ck_hs_set(3) function will store the key specified by the key argu-
     ment in the hash set pointed to by the hs argument. The key specified by
     key is expected to have the hash value specified by the hash argument
     (which was previously generated using the CK_HS_HASH(3) macro).

     If the call to ck_hs_set(3) was successful then the key specified by key
     was successfully stored in the hash set pointed to by hs.  If the key
     already exists in the hash set, then it is replaced by key and the previ-
     ous value is stored into the void pointer pointed to by the previous
     argument. If previous is set to NULL then key was not a replacement for
     an existing entry in the hash set.

     Upon successful completion, ck_hs_set(3) returns true and otherwise
     returns false on failure.

     Behavior is undefined if key or hs are uninitialized. The function will
     also return false if the hash set could not be enlarged to accomodate key
