46 * Common constants and type declarations for Sprite.
54 * A boolean type is defined as an integer, not an enum. This allows a
55 * boolean argument to be an expression that isn't strictly 0 or 1 valued.
67 * Functions that must return a status can return a ReturnStatus to
68 * indicate success or type of failure.
71 typedef int ReturnStatus;
74 * The following statuses overlap with the first 2 generic statuses
75 * defined in status.h:
77 * SUCCESS There was no error.
78 * FAILURE There was a general error.
81 #define SUCCESS 0x00000000
82 #define FAILURE 0x00000001
86 * A nil pointer must be something that will cause an exception if
87 * referenced. There are two nils: the kernels nil and the nil used
98 * An address is just a pointer in C. It is defined as a character pointer
99 * so that address arithmetic will work properly, a byte at a time.
102 typedef char *Address;
105 * ClientData is an uninterpreted word. It is defined as an int so that
106 * kdbx will not interpret client data as a string. Unlike an "Address",
107 * client data will generally not be used in arithmetic.
108 * But we don't have kdbx anymore so we define it as void (christos)
111 typedef void *ClientData;
