was returning a pointer into the stack!
change to use bt_cur as bt_search does

if DB_LOCK not set, pin page across calls and don't copy key/data pair

4.4BSD snapshot (revision 8.1); add 1993 to copyright

break BTF flags up into btree/recno (B_, R_) categories

bcmp/bcopy/bzero -> memcmp/memmove/memset

index -> indx_t

move db.h to the end of the includes, make compat.h work better

clear the stack in the search routine; it's a lot simpler

just clear the stack in on entry to put instead of trying to
clear it when it's used

R_CURSOR fails if cursor not initialized or if cursor deleted

lint cleanup, prettiness polic, add R_SETCURSOR

bcopy the pgno/size for overflow pages, may not be long aligned
flag all overflow pages with P_OVERFLOW, not just the first one.

If two keys compare equal, return the index of the matching key
not the next index. Test case is inserting two identical keys
into the database at the beginning of a page (before anything else).

fix overflow checking code to always keep the key in memory, if possible
and take into account both key and data; add MODIFIED bit; fix maxkepage and
minkeypage (bt_ovflsize)

Rev #2. Redo the btree code add recno's and checkpoint

ANSI prototypes

fix stack management bug
