What actually belongs to the "character type" in C11 — besides char
of course?
To be more precise, the special exceptions for the character type (for example that any object can be accessed by an lvalue expression of character type — see §6.5/7 in C11 standard), to which concrete types do they apply? They seem to apply to uint8_t
and int8_t
from stdint.h
, but is this guaranteed? On the other hand gcc doesn't regard char16_t
from uchar.h
as a "character type".
Only char
, signed char
and unsigned char
1.
The types uint8_t
, int8_t
, char16_t
, or any type in the form intN_t
or charN_t
, may or may not be synonyms for a character type.
1(Quoted from: ISO/IEC 9899:201x 6.2.5 Types 15)
The three types char, signed char, and unsigned char are collectively called the character types.
