+#=====================#
+# Fowler/Noll/Vo hash #
+#=====================#
+
+The basis of this hash algorithm was taken from an idea sent
+as reviewer comments to the IEEE POSIX P1003.2 committee by:
+
+ Phong Vo (http://www.research.att.com/info/kpv)
+ Glenn Fowler (http://www.research.att.com/~gsf/)
+
+In a subsequent ballot round:
+
+ Landon Curt Noll (http://www.isthe.com/chongo)
+
+improved on their algorithm. Some people tried this hash
+and found that it worked rather well. In an EMail message
+to Landon, they named it the ``Fowler/Noll/Vo'' or FNV hash.
+
+FNV hashes are designed to be fast while maintaining a low
+collision rate. The FNV speed allows one to quickly hash lots
+of data while maintaining a reasonable collision rate. See:
+
+ http://www.isthe.com/chongo/tech/comp/fnv/index.html
+
+for more details as well as other forms of the FNV hash.
+Comments, questions, bug fixes and suggestions welcome at
+the address given in the above URL.
+
+
+#==================#
+# FNV hash utility #
+#==================#
+
+Two hash utilities (32 bit and 64 bit) are provided:
+
+ fnv032 [-b bcnt] [-m] [-s arg] [-t code] [-v] [arg ...]
+ fnv132 [-b bcnt] [-m] [-s arg] [-t code] [-v] [arg ...]
+ fnv1a32 [-b bcnt] [-m] [-s arg] [-t code] [-v] [arg ...]
+
+ fnv064 [-b bcnt] [-m] [-s arg] [-t code] [-v] [arg ...]
+ fnv164 [-b bcnt] [-m] [-s arg] [-t code] [-v] [arg ...]
+ fnv1a64 [-b bcnt] [-m] [-s arg] [-t code] [-v] [arg ...]
+
+ -b bcnt mask off all but the lower bcnt bits (default: 32)
+ -m multiple hashes, one per line for each arg
+ -s hash arg as a string (ignoring terminating NUL bytes)
+ -t code 0 ==> generate test vectors, 1 ==> test FNV hash
+ -v verbose mode, print arg after hash (implies -m)
+ arg string (if -s was given) or filename (default stdin)
+
+The fnv032, fnv064 implement the historic FNV-0 hash.
+The fnv132, fnv164 implement the recommended FNV-1 hash.
+The fnv1a32, fnv1a64 implement the recommended FNV-1a hash.
+
+This is the original historic FNV algorithm with a 0 offset basis.
+It is recommended that FNV-1, with a non-0 offset basis be used instead.
+
+To test FNV hashes, try:
+
+ fnv032 -t 1 -v
+ fnv132 -t 1 -v
+ fnv1a32 -t 1 -v
+
+ fnv064 -t 1 -v
+ fnv164 -t 1 -v
+ fnv1a64 -t 1 -v
+
+If you are compiling, try:
+
+ make check
+
+
+#==================#
+# FNV hash library #
+#==================#
+
+The libfnv.a library implements both a 32 bit and a 64 bit FNV hash
+on collections of bytes, a NUL terminated strings or on an open file
+descriptor.
+
+Here is the 32 bit FNV 1 hash:
+
+ Fnv32_t fnv_32_buf(void *buf, int len, Fnv32_t hval); /* byte buf */
+ Fnv32_t fnv_32_str(char *string, Fnv32_t hval); /* string */
+
+Here is the 32 bit FNV 1a hash:
+
+ Fnv32_t fnv_32a_buf(void *buf, int len, Fnv32_t hval); /* byte buf */
+ Fnv32_t fnv_32a_str(char *string, Fnv32_t hval); /* string */
+
+Here is the 64 bit FNV 1 hash:
+
+ Fnv64_t fnv_64_buf(void *buf, int len, Fnv64_t hval); /* byte buf */
+ Fnv64_t fnv_64_str(char *string, Fnv64_t hval); /* string */
+
+Here is the 64 bit FNV 1a hash:
+
+ Fnv64_t fnv_64a_buf(void *buf, int len, Fnv64_t hval); /* byte buf */
+ Fnv64_t fnv_64a_str(char *string, Fnv64_t hval); /* string */
+
+On the first call to a hash function, one must supply the initial basis
+that is appropriate for the hash in question:
+
+ FNV-0: (not recommended)
+
+ FNV0_32_INIT /* 32 bit FNV-0 initial basis */
+ FNV0_64_INIT /* 64 bit FNV-0 initial basis */
+
+ FNV-1:
+
+ FNV1_32_INIT /* 32 bit FNV-1 initial basis */
+ FNV1_64_INIT /* 64 bit FNV-1 initial basis */
+
+ FNV-1a:
+
+ FNV1A_32_INIT /* 32 bit FNV-1a initial basis */
+ FNV1A_64_INIT /* 64 bit FNV-1a initial basis */
+
+For example to perform a 64 bit FNV-1 hash:
+
+ #include "fnv.h"
+
+ Fnv64_t hash_val;
+
+ hash_val = fnv_64_str("a string", FNV1_64_INIT);
+ hash_val = fnv_64_str("more string", hash_val);
+
+produces the same final hash value as:
+
+ hash_val = fnv_64_str("a stringmore string", FNV1_64_INIT);
+
+NOTE: If one used 'FNV0_64_INIT' instead of 'FNV1_64_INIT' one would get the
+ historic FNV-0 hash instead recommended FNV-1 hash.
+
+To perform a 32 bit FNV-1 hash:
+
+ #include "fnv.h"
+
+ Fnv32_t hash_val;
+
+ hash_val = fnv_32_buf(buf, length_of_buf, FNV1_32_INIT);
+ hash_val = fnv_32_str("more data", hash_val);
+
+To perform a 64 bit FNV-1a hash:
+
+ #include "fnv.h"
+
+ Fnv64_t hash_val;
+
+ hash_val = fnv_64a_buf(buf, length_of_buf, FNV1_64_INIT);
+ hash_val = fnv_64a_str("more data", hash_val);

+ * Fowler/Noll/Vo hash
+ *
+ * The basis of this hash algorithm was taken from an idea sent
+ * as reviewer comments to the IEEE POSIX P1003.2 committee by:
+ *
+ * Phong Vo (http://www.research.att.com/info/kpv/)
+ * Glenn Fowler (http://www.research.att.com/~gsf/)
+ *
+ * In a subsequent ballot round:
+ *
+ * Landon Curt Noll (http://www.isthe.com/chongo/)
+ *
+ * improved on their algorithm. Some people tried this hash
+ * and found that it worked rather well. In an EMail message
+ * to Landon, they named it the ``Fowler/Noll/Vo'' or FNV hash.
+ *
+ * FNV hashes are designed to be fast while maintaining a low
+ * collision rate. The FNV speed allows one to quickly hash lots
+ * of data while maintaining a reasonable collision rate. See:
+ *
+ * http://www.isthe.com/chongo/tech/comp/fnv/index.html
+ *
+ * for more details as well as other forms of the FNV hash.
