# convertible _ int(type , headers = nil , opts = nil) (6117.0) -
Returns the convertible integer type of the given +type+. You may optionally specify additional +headers+ to search in for the +type+. _Convertible_ means actually same type, or typedefed from same type. If the +type+ is a integer type and _convertible_ type is found, following macros are passed as preprocessor constants to the compiler using the +type+ name, in uppercase. * 'TYPEOF_', followed by the +type+ name, followed by '=X' where 'X' is the found _convertible_ type name. * 'TYP2NUM' and 'NUM2TYP, where 'TYP' is the +type+ name in uppercase with replacing '_t' suffix with 'T', followed by '=X' where 'X' is the macro name to convert +type+ to +Integer+ object, and vice versa. For example, if foobar_t is defined as unsigned long, then convertible_int("foobar_t") would return "unsigned long", and define macros: #define TYPEOF_FOOBAR_T unsigned long #define FOOBART2NUM ULONG2NUM #define NUM2FOOBART NUM2ULONG
