[Numpy-discussion] Question about numarray Bool type

[Peter V. <ve...@em...>]

Hi,

In the numarray source code Bool is defined as a typedef to char. Does th=
e=20
Bool array type correspond to the Int8, or the UInt8 type? If I recall=20
correctly, the char type may be signed or unsigned. Can I make any=20
assumptions about the C type used to implement Bool at all?

I guess at the Python level it does not matter what actual C type is used=
 to=20
implement bool arrays as it only represents boolean values. However, at t=
he=20
level of C extensions I would like to deal with Bool arrays by calling=20
existing functions written for the appropiate C type. That would be somew=
hat=20
simpler if Bool is always garantueed to be either a unsigned or a signed =
char=20
type.=20

Cheers, Peter.
