Converting python string object to c char* using ctypes

Thanks to Eryksun the solution:

Python code

string1 = "my string 1"
string2 = "my string 2"

# create byte objects from the strings
b_string1 = string1.encode('utf-8')
b_string2 = string2.encode('utf-8')

# send strings to c function
my_c_function.argtypes = [ctypes.c_char_p, ctypes.char_p]
my_c_function(b_string1, b_string2)
