CK_RHS_REMOVE(3)      DragonFly Library Functions Manual      CK_RHS_REMOVE(3)


NAME

     ck_rhs_remove - remove key from a hash set


LIBRARY

     Concurrency Kit (libck, -lck)


SYNOPSIS

     #include <ck_rhs.h>

     void *
     ck_rhs_remove(ck_rhs_t *hs, unsigned long hash, const void *key);


DESCRIPTION

     The ck_rhs_remove(3) function will attempt to remove the key specified by
     the key argument 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_RHS_HASH(3) macro).

     If the call to ck_rhs_remove(3) was successful then the key contained in
     the hash set is returned. If the key was not a member of the hash set
     then NULL is returned.


RETURN VALUES

     Upon successful completion, ck_rhs_remove(3) returns a pointer to a key
     and otherwise returns NULL on failure.


ERRORS

     Behavior is undefined if key or hs are uninitialized.
