convertible_int

Returns the convertible integer type of the given type. You may optionally specify additional headers to search in for the type. convertible means actually the same type, or typedef'd from the same type.

If the type is a integer type and the convertible type is found, the 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 âXâ is the found convertible type name.

• TYP2NUM and NUM2TYP, where TYP is the type name in uppercase with replacing an _t suffix with âTâ, followed by =X where âXâ is the macro name to convert type to an Integer object, and vice versa.

For example, if foobar_t is defined as unsigned long, then convertible_int("foobar_t") would return âunsigned longâ, and define these macros:

#define TYPEOF_FOOBAR_T unsigned long
#define FOOBART2NUM ULONG2NUM
#define NUM2FOOBART NUM2ULONG
