NetBSD 6.1.5 - man page for hash32_str (netbsd section 9)

HASH(9) 			  BSD Kernel Developer's Manual 			  HASH(9)

NAME
     hash, hash32_buf, hash32_str, hash32_strn -- kernel hash functions

SYNOPSIS
     #include <sys/types.h>
     #include <sys/hash.h>

     uint32_t
     hash32_buf(const void *buf, size_t len, uint32_t ihash);

     uint32_t
     hash32_str(const void *buf, uint32_t ihash);

     uint32_t
     hash32_strn(const void *buf, size_t len, uint32_t ihash);

DESCRIPTION
     The hash functions returns a hash of the given buffer.

     The hash32_buf() function returns a 32 bit hash of buf, which is len bytes long, seeded with
     an initial hash of ihash (which is usually HASH32_BUF_INIT).  This function may use a dif-
     ferent algorithm to hash32_str() and hash32_strn().

     The hash32_str() function returns a 32 bit hash of buf, which is a NUL terminated ASCII
     string, seeded with an initial hash of ihash (which is usually HASH32_STR_INIT).  This func-
     tion must use the same algorithm as hash32_strn(), so that the same data returns the same
     hash.

     The hash32_strn() function returns a 32 bit hash of buf, which is a NUL terminated ASCII
     string, up to a maximum of len bytes, seeded with an initial hash of ihash (which is usually
     HASH32_STR_INIT).	This function must use the same algorithm as hash32_str(), so that the
     same data returns the same hash.

     The ihash parameter is provided to allow for incremental hashing by allowing successive
     calls to use a previous hash value.

RETURN VALUES
     The hash32_* functions return a 32 bit hash of the provided buffer.

HISTORY
     The kernel hashing API first appeared in NetBSD 1.6.
