HASHINIT(9) BSD Kernel Manual HASHINIT(9)NAMEhashinit - kernel hashtable functions
SYNOPSIS
#include <sys/systm.h>
void *
hashinit(int num, int type, int flags, u_long *mask);
DESCRIPTION
The 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) func-
tion unchanged. The mask argument is used to pass back the mask for use
with the allocated hashing table. For an example of its use, see hash(9).
RETURN VALUES
The hashinit() function returns a pointer to the allocated and initial-
ized hash table.
SEE ALSOfree(9), hash(9), malloc(9)LIMITATIONS
The hashinit() function currently only allocates hash tables with LIST
bucket pointers at this time. Future enhancements to allocate QUEUE buck-
et pointers may be warranted. This may necessitate an API change to ac-
commodate.
HISTORY
The hashinit function first appeared in 4.4BSD.
