uint16_t and
int16_t are optional integer types of exactly 16 bits. Both types
have no padding, and
int16_t uses 2's complement.
uint16_t is unsigned, and has the range zero to
UINT16_, which is [0, +65535].
int16_t is signed, and has the range
INT16_ to
INT16_, which is [−32768, +32767].
The following macros can be used in the fmt argument of printf to print arguments of types
uint16_t and
int16_t:
PRIu16PRIo16PRIx16PRIX16PRId16PRIi16
The following macros can be used in the fmt argument of scanf to scan arguments of types
uint16_t * and
int16_t *:
SCNu16SCNo16SCNx16SCNd16SCNi16
The existence of macros such as
PRIu16 can be used to detect the existence of
uint16_t with conditional compilation.
