I think the arguments should be copied and explicitly cast. It's nasty, but crossing boundaries always is. There are some old compatibility functions in numpy that do the same thing. Isn't this a bit conservative? It looks to me like long and double would be good bets for a lot of these. The boolean type, '?', is also missing. 186 187 ctypedef signed int npy_byte 188 ctypedef signed int npy_short 189 ctypedef signed int npy_int 190 ctypedef signed int npy_long 191 ctypedef signed int npy_longlong 192 193 ctypedef unsigned int npy_ubyte 194 ctypedef unsigned int npy_ushort 195 ctypedef unsigned int npy_uint 196 ctypedef unsigned int npy_ulong 197 ctypedef unsigned int npy_ulonglong 198 199 ctypedef float npy_float 200 ctypedef float npy_double 201 ctypedef float npy_longdouble 202 203 ctypedef signed int npy_int8 204 ctypedef signed int npy_int16 205 ctypedef signed int npy_int32 206 ctypedef signed int npy_int64 207 ctypedef signed int npy_int96 208 ctypedef signed int npy_int128 209 210 ctypedef unsigned int npy_uint8 211 ctypedef unsigned int npy_uint16 212 ctypedef unsigned int npy_uint32 213 ctypedef unsigned int npy_uint64 214 ctypedef unsigned int npy_uint96 215 ctypedef unsigned int npy_uint128 216 217 ctypedef float npy_float32 218 ctypedef float npy_float64 219 ctypedef float npy_float80 220 ctypedef float npy_float96 221 ctypedef float npy_float128 Chuck
