Issue Date: 20/12/2007
|
||||
|
||||
The unsigned integer types defined here are of the form uint_<nn>t where
|
||||
<nn> is the length of the type; for example, the unsigned 32-bit type is
|
||||
'uint_32t'. These are NOT the same as the 'C99 integer types' that are
|
||||
defined in the inttypes.h and stdint.h headers since attempts to use these
|
||||
types have shown that support for them is still highly variable. However,
|
||||
since the latter are of the form uint<nn>_t, a regular expression search
|
||||
and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
|
||||
can be used to convert the types used here to the C99 standard types.
