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.
