53 * A boolean type is defined as an integer, not an enum. This allows a
54 * boolean argument to be an expression that isn't strictly 0 or 1 valued.
57 typedef int Boolean;
58 #ifndef TRUE
59 #define TRUE 1
60 #endif /* TRUE */
61 #ifndef FALSE
62 #define FALSE 0
63 #endif /* FALSE */
66 * Functions that must return a status can return a ReturnStatus to
67 * indicate success or type of failure.
70 typedef int ReturnStatus;
73 * The following statuses overlap with the first 2 generic statuses
74 * defined in status.h:
76 * SUCCESS There was no error.
77 * FAILURE There was a general error.
80 #define SUCCESS 0x00000000
81 #define FAILURE 0x00000001
85 * A nil pointer must be something that will cause an exception if
86 * referenced. There are two nils: the kernels nil and the nil used
87 * by user processes.
90 #define NIL ~0
91 #define USER_NIL 0
94 * An address is just a pointer in C. It is defined as a character pointer
95 * so that address arithmetic will work properly, a byte at a time.
98 typedef char *Address;
101 * ClientData is an uninterpreted word. It is defined as an int so that
102 * kdbx will not interpret client data as a string. Unlike an "Address",
103 * client data will generally not be used in arithmetic.
104 * But we don't have kdbx anymore so we define it as void (christos)
107 typedef void *ClientData;
