Subject: [issue1962] ctypes feature request: Automatic type conversion of input
arguments to C functions
Amaury Forgeot d'Arc <amauryfa@gmail.com> added the comment:
I don't think this should happen by default.
but what the user wants is already possible, by using the from_param() method.
For example, the AutoStrParam type converts everything to a string (and a
char*):
from ctypes import *
class AutoStrParam(c_char_p):
@classmethod
def from_param(cls, value):
return str(value)
strlen = cdll.LoadLibrary('msvcrt').strlen
strlen.argtypes = [AutoStrParam]
print strlen(None) # "None" -> 4
print strlen(type) # "<type 'type'>" -> 13
