31 * Begin mapping section
33 * There are some mappings between integer values (enums) and strings
34 * to be presented to user. To make it easier to convert between those two
35 * set of macros is given. It is specially useful when we want to have
36 * strings that match constants from header files like:
37 * BT_STATUS_SUCCESS (0) and corresponding "BT_STATUS_SUCCESS"
40 * INTMAP(int, -1, "invalid")
41 * DELEMENT(BT_STATUS_SUCCESS)
42 * DELEMENT(BT_STATUS_FAIL)
43 * MELEMENT(123, "Some strange value")
46 * Just by doing this we have mapping table plus two functions:
47 * int str2int(const char *str);
48 * const char *int2str(int v);
50 * second argument to INTMAP specifies value to be returned from
51 * str2int function when there is not mapping for such number
52 * third argument specifies default value to be returned from int2str
54 * If same mapping is to be used in several source files put
55 * INTMAP in c file and DECINTMAP in h file.
57 * For mappings that are to be used in single file only
58 * use SINTMAP which will create the same but everything will be marked
