Changes in 4.42:

Obsolete functions.

dt_fp_size(), dt_fp_setsize().
dt_fp_minsize(), dt_fp_setminsize().
dt_fp_mindensity(), dt_fp_setmindensity().
dt_fp_alloc(), dt_fp_fingerprint(), dt_fp_fold().

New functions.

dt_fp_allocfp(dt_Integer size) => dt_Handle fp

• Allocates a new, empty fingerprint of the given size (in bits).

dt_fp_generatefp(dt_Handle ob, dt_Integer minpath, dt_Integer maxpath, dt_Integer size) => dt_Handle fp

• Creates and fills in a fingerprint of the given size based on 'ob'.
• Minpath and maxpath set the inclusive range of path lengths used in the bit-generation step.
• dt_fp_generatefp(ob, 0, 7, size) == dt_fp_fingerprint(ob, FALSE).

dt_fp_foldfp(dt_Handle fp, dt_Integer minsize, dt_Real density) => dt_Boolean ok

• Folds the given fingerprint object zero or more times until the size is minsize or the bit density is above 'density'.

dt_fp_bitvalue(dt_Handle fp, dt_Integer bitno) => dt_Integer value dt_fp_setbitvalue(dt_Handle fp, dt_Integer bitno, dt_Integer value) => dt_Boolean ok

• Gets or sets the current value (0 or 1) of a bit in a fingerprint.
