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 lib header   What s the best way to have these types on my application source code

User · Answer

Those integer types are all defined in stdint h

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

The C99 stdint h defines these    int8 t int16 t int32 t uint8 t uint16 t uint32 t   And  if the architecture supports them    int64 t uint64 t   There are various other integer typedefs in stdint h as well   If you re stuck without a C99 environment then you should probably supply your own typedefs and use the C99 ones anyway   The uint32 and uint64  i e  without the  t suffix  are probably application specific

If you are using C99 just include stdint h  BTW  the 64bit types are there iff the processor supports them

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