|HASHINIT(9)||Kernel Developer's Manual||HASHINIT(9)|
num, int type,
*hash, int num,
hashinit() function is used to allocate a hashtable of a desired size given by the num argument. The
hashinit() function will round this number to the next power of two, and allocate and initialize the requested hashtable. The type and flags arguments are passed to the malloc(9) function unchanged. The mask argument is used to pass back the mask for use with the allocated hashing table.
hashfree() function causes memory
allocated by the
hashinit() function to be released.
The num and type arguments of
related calls must match.
hashinit() function returns a pointer to the allocated and initialized hash table.
hashinit() function currently only allocates hash tables with LIST bucket pointers at this time. Future enhancements to allocate QUEUE bucket pointers may be warranted. This may necessitate an API change to accommodate.
hashinitfunction first appeared in 4.4BSD.
