C Language X-macros Enum Value and Identifier
Example
/* declare items of the enum */
#define FOREACH \
X(item1) \
X(item2) \
X(item3) \
/* end of list */
/* define the enum values */
#define X(id) MyEnum_ ## id,
enum MyEnum { FOREACH };
#undef X
/* convert an enum value to its identifier */
const char * enum2string(int enumValue)
{
const char* stringValue = NULL;
#define X(id) if (enumValue == MyEnum_ ## id) stringValue = #id;
FOREACH
#undef X
return stringValue;
}
Next you can use the enumerated value in your code and easily print its identifier using :
printf("%s\n", enum2string(MyEnum_item2));
