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