NAME

SYNOPSIS
#include <btree.h>
void *btcursor(btp)
btree_t *btp;
DESCRIPTION
btcursor is used to determine if the cursor for btree btp is currently
positioned on a key or is null. If the cursor is set to null, the
NULL pointer is returned. If the cursor is positioned to a key, a
non-NULL value is returned. If btp does not point to a valid open
btree, the results are undefined. btcursor is a macro.
