Are types like uint32, int32, uint64, int64 defined in any stdlib header?

Question

I often see source code using types like uint32, uint64 and I wonder if they should be defined by the programmer in the application code or if they are defined in a standard

Answer 1

The questioner actually asked about int16 (etc) rather than (ugly) int16_t (etc).

There are no standard headers - nor any in Linux's /usr/include/ folder that define them without the "_t".
