_Atomic (C11)
_BitInt (C23)
_Bool (C99)
_Complex (C99)
_Decimal128 (C23)

The most common keywords that begin with an underscore are generally used through their convenience macros:

- - - - - - - - - - - - - - - - -
keyword used as defined in
-_Alignas (C11) -alignas (removed in C23) -stdalign.h
-_Alignof (C11) -alignof (removed in C23) -stdalign.h
-_Atomic (C11) -atomic_bool, atomic_int, ... -stdatomic.h
-_BitInt (C23) (no macro)
-_Bool (C99) -bool (removed in C23) -stdbool.h
-_Complex (C99) -complex -complex.h
-_Decimal128 (C23) (no macro)
-_Decimal32 (C23) (no macro)
-_Decimal64 (C23) (no macro)
-_Generic (C11) (no macro)
-_Imaginary (C99) -imaginary -complex.h
-_Noreturn (C11) -noreturn -stdnoreturn.h
-_Static_assert (C11) -static_assert (removed in C23) -assert.h
-_Thread_local (C11) -thread_local (removed in C23) -threads.h

Also, each name that begins with a double underscore __ or an underscore _ followed by an uppercase letter is reserved: see identifier for details.

-

Note that digraphs <%, %>, <:, :>, %:, and %:%: provide an alternative way to represent standard tokens.

-

The following tokens are recognized by the preprocessor when they are used within the context of a preprocessor directive:

- - -

if
elif
else
endif

-

ifdef
ifndef
elifdef (C23)
elifndef (C23)
define
undef

-

include
embed (C23)
line
error
warning (C23)
pragma

-

defined
__has_include (C23)
__has_embed (C23)
__has_c_attribute (C23)

-

The following tokens are recognized by the preprocessor when they are used outside the context of a preprocessor directive:

- - -

_Pragma (C99)

-

The following additional keywords are classified as extensions and conditionally-supported:

- - -

asm
fortran
