Hi,
In the numarray source code Bool is defined as a typedef to char. Does the
Bool array type correspond to the Int8, or the UInt8 type? If I recall
correctly, the char type may be signed or unsigned. Can I make any
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
implement bool arrays as it only represents boolean values. However, at the
level of C extensions I would like to deal with Bool arrays by calling
existing functions written for the appropiate C type. That would be somewhat
simpler if Bool is always garantueed to be either a unsigned or a signed char
type.
Cheers, Peter.
