Enumeration Type Documentation

enum int_type

Encoding of integer types. The upper 3rd byte encodes the integer conversion rank of the integer type. See standard ISO/IEC 9899:1999 6.3.1.1 The upper 2nd byte contains the size of the type. The lowest byte encodes the signedness of the type, 0 = unsigned, 1 = signed.
