I need run a c++ method from my python program
but the c++ method need a few parameters
what need for call that method in my python code with the paramethers
Here is a code example ...
# using the module ctypes you can access DLLs written in C/C++ # ctypes converts between Python types and C types # there are two ways to write DLLs: # most common uses cdecl, import with cdll # Win and VB may use stdcall, import with windll # module ctypes is built into Python25 and higher # look under ctypes in the Python manual from ctypes import * # as an example let's use msvcrt.dll # this is the MS C library containing many standard C functions # import the C function strchr() from msvcrt.dll strchr = cdll.msvcrt.strchr # declare the return type ... # a 'pointer to a string' (which then converts to a Python string) strchr.restype = c_char_p # these are the argument types ... # Python string converts to 'pointer to a string' --> c_char_p # Python single char string converts to C char --> c_char strchr.argtypes = [c_char_p, c_char] # now call the function and show the result print strchr('abcdefg', 'd') # result --> defg # some C functions are easier to access ... printf = cdll.msvcrt.printf printf("Hello, %s\n", "World!")
