// We define V_{-1} = -\infty and
// V_{|V|} = \infty and
// h(-\infty,extra_h) = -1 by definition and
// h( \infty,extra_h) = 1 by definition
// Requires: Direction != 0
// Effect:
// if direction >0 then find the smallest i such that h(V_i,extra_h)>=0.
// if direction <0 then find the largest i such that h(V_i,extra_h)<=0.
// Let signus(r_h) = signus(h(V_i, extra_h))
// If flags&(DB_PRELOCKED|DB_PRELOCKED_WRITE) then skip locking
// That is, we already own the locks
// else
// if direction >0 then readlock [V_{i-1}, V_i]
// if direction <0 then readlock [V_i, V_{i+1}]
// That is, If we search from the right, lock the element we found, up to the
// next element to the right.
// If locking fails, return the locking error code
//
// If (0<=i<|V|) then
// call f(V_i.Key, V_i.Value, extra_f, r_h)
// Note: The lifetime of V_i.Key and V_i.Value is limited: they may only
// be referenced until f returns
// and return 0
// else
// return DB_NOTFOUND
// Rationale: Locking
// If we approach from the left (direction<0) we need to prevent anyone
// from inserting anything to our right that could change our answer,
// so we lock the range from the element found, to the next element to the right.
// The inverse argument applies for approaching from the right.
// Rationale: passing r_h to f
// We want to save the performance hit of requiring f to call h again to
// find out what h's return value was.
// Rationale: separate extra_f, extra_h parameters
// If the same extra parameter is sent to both f and h, then you need a
// special struct for each tuple (f_i, h_i) you use instead of a struct for each
// f_i and each h_i.
// Requires: The signum of h is monotically increasing.
// Requires: f does not create references to key, value, or data within once f
// exits
// Returns
// 0 success
// DB_NOTFOUND i is not in [0,|V|)
// DB_LOCK_NOTGRANTED Failed to obtain a lock.
// On nonzero return, what c points to becomes undefined, That is, c becomes uninitialized
// Performance: ... TODO
// Implementation Notes:
// How do we get the extra locking information efficiently?
// After finding the target, we can copy the cursor, do a DB_NEXT,
// or do a DB_NEXT+DB_PREV (vice versa for direction<0).
// Can we have the BRT provide two key/value pairs instead of one?
// That is, brt_cursor_c_getf_heavi_and_next for direction >0
// and brt_cursor_c_getf_heavi_and_prev for direction <0
// Current suggestion is to make a copy of the cursor, and use the
// copy to find the next(prev) element by using DB_NEXT(DB_PREV).
// This has the overhead of needing to make a copy of the cursor,
// which probably has a memcpy involved.
// The argument against returning two key/value pairs is that
// we should not have to pay to retreive both when we're doing something
// simple like DB_NEXT.
// This could be mitigated by having two BRT functions (or one with a
// BOOL parameter) such that it only returns two values when necessary.
// Parameters
// c The cursor
// flags Additional bool parameters. The current allowed flags are
// DB_PRELOCKED and DB_PRELOCKED_WRITE (bitwise or'd to use both)
// h A heaviside function that, along with direction, defines the query.
// extra_h is passed to h
// For additional information on heaviside functions, see omt.h
// NOTE: In a DB_DUPSORT database, both key and value will be
// passed to h. In a NODUP database, only key will be passed to h.
// f A callback function (i.e. smart dbts) to provide the result of the
// query. key and value are the key/value pair found, extra_f is
// passed to f, r_h is the return value for h for the key and value returned.
// This is used as output. That is, we call f with the outputs of the
// function.
// direction Which direction to search in on the heaviside function. >0
// means from the right, <0 means from the left.
// extra_f Any extra information required for f
// extra_h Any extra information required for h
//
// Example:
// Find the smallest V_i = (key_i,val_i) such that key_i > key_x, assume
// key.data and val.data are c strings, and print them out.
// Create a struct to hold key_x, that is extra_h
// Direction = 1 (We approach from the right, and want the smallest such
// element).
// Construct a heaviside function that returns >=0 if the
// given key > key_x, and -1 otherwise
// That is, call the comparison function on (key, key_x)
// Create a struct to hold key_x, that is extra_f
// construct f to call printf on key_x.data, key_i.data, val_i.data.
// Find the least upper bound (greatest lower bound)
// In this case, h can just return the comparison function's answer.
// direction >0 means upper bound, direction <0 means lower bound.
// (If you want upper/lower bound of the keyvalue pair, you need
// to call the comparison function on the values if the key comparison
// returns 0).
// Handlerton implications:
// The handlerton needs at most one heaviside function per special query type (where a
// special query is one that is not directly supported by the bdb api excluding
// this function).
// It is possible that more than query type can use the same heaviside function
// if the extra_h parameter can be used to change its behavior sufficiently.
//
// That is, part of extra_h can be a boolean strictly_greater
// You can construct a single heaviside function that converts 0 to -1
// (strictly greater) from the comparison function, or one that just returns
// the results of the comparison function (greater or equal).
//
// Implementation Notes:
// The BRT search function supports the following searches:
// SEARCH_LEFT(h(V_i))
// Given a step function b, that goes from 0 to 1
// find the greatest i such that h_b(V_i) == 1
// If it does not exist, return not found
// SEARCH_RIGHT(h(V_i))
// Given a step function b, that goes from 1 to 0
// find the smallest i such that h_b(V_i) == 1
// If it does not exist, return not found
// We can implement c_getf_heavi using these BRT search functions.
// A query of direction<0:
// Create wrapper function B
// return h(V_i) <=0 ? 1 : 0;
// SEARCH_RIGHT(B)
// A query of direction>0:
// Create wrapper function B
// return h(V_i) >=0 ? 1 : 0;
// SEARCH_LEFT(B)
// Effect: Lightweight cursor get
