#define DBG_CANARY 0xca96ca96 |
Value to be set in sacrificial "canary" fields. If this value is not as expected, the canaryu has been killed by something inappropriately stomping on memory.

#define DBG_CANARY_ENTRY int32 canary; |
Defines a canary element in a data structure.

Value:
if (i >= (x).dbgelems) {\ elog(ERROR, "Element index out of range %d", i); }

#define EMPTY 1 |
Base size for an array containing a canary. This is zero if VEIL_DEBUG is not defined, iw when this is defined arrays will be one element longer to allow a canary to be placed at the end of the array.
Definition at line 67 of file veil_datatypes.h.
#define HASH_KEYLEN 60 |
The key length for veil hash types.

#define VEIL_DEBUG 1 |
Enables various debugging constructs, such as canaries, in code and data structures. If such debugging is required, define VEIL_DEBUG in the make invocation, eg: "make VEIL_DEBUG=1".
Definition at line 23 of file veil_datatypes.h.
enum ObjType |
Describes the type of an Object record or one of its subtypes.
