CK_RHS_SET(3) BSD Library Functions Manual CK_RHS_SET(3)NAMEck_rhs_set — store key into a hash set
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_rhs.h>
bool
ck_rhs_set(ck_rhs_t *hs, unsigned long hash, const void *key,
void **previous);
DESCRIPTION
The ck_rhs_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_RHS_HASH(3) macro).
If the call to ck_rhs_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.
RETURN VALUES
Upon successful completion, ck_rhs_set(3) returns true and otherwise
returns false on failure.
ERRORS
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
insertion.
