// Requires: p != NULL
// Returns:
// 0 success
// ENOMEM out of memory (and doesn't modify *omtp)
// Performance: constant time.

// associated with *p.
// Also sets *p=NULL.
// Rationale: The usage is to do something like
// toku_omt_cursor_destroy(&c);
// and now c will have a NULL pointer instead of a dangling freed pointer.
// Rationale: Returns no values since free() cannot fail.

// On nonzero return, *v is unchanged and c is invalidated.
// Performance: time=O(log N) worst case, expected time=O(1) for a randomly
// chosen initial position.

// On nonzero return, *index is unchanged and c is unchanged.
// Performance: time=O(1)
OMT toku_omt_cursor_get_omt(OMTCURSOR c);

// Performance: time=O(1)

// Effect: Store in v the value pointed by c's abstract offset
// Requires: v != NULL
// Returns

// On non-zero return, *v is unchanged
// Performance: O(1) time
int toku_omt_cursor_prev (OMTCURSOR c, OMTVALUE *v);
// Effect: Decrement c's offset, and find and store the value in v.
// Requires: v != NULL
// Returns
// 0 success
// EINVAL if the offset goes out of range or c is invalid.
// On nonzero return, *v is unchanged and c is invalidated.
// Performance: time=O(log N) worst case, expected time=O(1) for a randomly
// chosen initial position.
void toku_omt_cursor_invalidate (OMTCURSOR c);
// Effect: Invalidate c. (This does not mean that c is destroyed or
// that its memory is freed.)
// If c is valid, the invalidate callback function (if any) will be called
// before invalidating c.
void toku_omt_cursor_set_invalidate_callback(OMTCURSOR c, void (*f)(OMTCURSOR,void*), void* extra);
// Effect:
// Saves function 'f' to be called whenever the cursor is invalidated.
// 'extra' is passed as an additional parameter to f.
// Requires:
// The lifetime of the 'extra' parameter must continue at least till the cursor
// is destroyed.
void toku_omt_cursor_associate(OMT omt, OMTCURSOR c);
// Effect:
// Associates an omtcursor with an omt.
// Requires:
// The omtcursor is not associated with any other omt.
// Requires:
// toku_omt_associate must be called when the omt-lock is held
// Rationale:
// This is used by brt_cursors for omts representing leaf nodes.
// These omts are touched by multiple threads, and therefore require locks
// for modifying the list of omtcursors.
// We do not want to grab two locks (one for omt, and one for the old
// associated omt).
