Detailed Description

Macro Definition Documentation

#define MDB_DEBUG 0

Enable debug output. Needs variable argument macros (a C99 feature). Set this to 1 for copious tracing. Set to 2 to add dumps of all IDLs read from and written to the database (used for free space management).

#define DPUTS(arg) DPRINTF(('%s', arg))

Print a debug string. The string is printed literally, with no format processing.

#define DDBI(mc) (((mc)->mc_flags & C_SUB) ? -(int)(mc)->mc_dbi : (int)(mc)->mc_dbi)
