int bdbug(BTA* btact, char* opt, BTint blk);
The bdbug function provides a debug
capability for the B Tree package. The following options can
be passed via the opt parameter:
Table 3.1. Debug Options
| control | - | displays the in-memory block information, together with the last key found details |
| super | - | displays superroot information i.e. block usage, free list etc. |
| stack | - | displays the tree stack (i.e. key context) |
| space | - | displays occupancy statistics |
| stats | - | displays B Tree operating statistics |
| block | - | displays the
contents of the block identified by
blk. blk
is declared as a BTint, which is normally a typedef for
int, but with Large File Support
will be a typedef for long long.

A non-zero return from bdbug indicates an
error occurred during the display of debugging
information.
