I have a C function that does some pixel manipulation on a raw 2D array of 8 bit RGB values. I get the response in 开发者_StackOverflowa c_ubyte array. My code looks roughly like this:
I\'m trying to use Python\'s ctypes to work with a DLL, but I occasionally run into a problem when I try to call a function that\'s passed as a pointer to another function.
I\'ve written some function callbacks using python\'s ctypes to access functions in a DLL.The code used to build that DLL has some debugging print statements in it using fprintf to stderr.However, whe
When wrapping Python functions with a CFUNCTYPE type, I\'ve found that the non-pointer types are automatically converted as though their value attribute was called.
My python code is calling a C function in a native library (also written by me). The function takes two strings as arguments and returns its response as a string. The two argument strings that python
I understand how to define structs in Python with ctypes, but I can\'t seem to find any documentation on how to handle basic aliases. For example 64-bit integers in SQLite:
