[issue42880] ctypes: variadic function call still doesn't work on Apple Silicon

[Ronald Oussoren]

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:

AFAIK you should specify the types of the fixed arguments for variadic functions. The ABI for the M1 has a different calling convention of the variadic arguments, the ctypes implementation counts how many variadic arguments there are based on the specified number of fixed arguments.
