To test if a C type is signed or not, I wrote this macro:
// Test if a C type is signed.
//
// Usage: assert(_Py_CTYPE_IS_SIGNED(char)); // fail if 'char' type is unsigned
#define _Py_CTYPE_IS_SIGNED(T) (((T)-1) < 0)
I planned to use it to raise an error on "import audioop" if the C "char" type is unsigned, but it seems like it's not needed, since the C extensions seems to work if char is signed or unsigned (I only read the C code, I didn't run test_audioop to actually test it). |
