The returned object is a ctypes array of c_char. init_or_size must be an integer which specifies the size of the array, or a bytes object which will be used to initialize the array items.
WebMay 19, 2015 · c_char_p is a null-terminated string in ctypes (specifically this simple C type is a subclass of ctypes._SimpleCData defined with _type_ == 'z' ). Use count = c_int (); backends = POINTER (c_char_p) () . That's a single pointer to a null-terminated string. WebApr 11, 2024 · 在该头文件里,定义了LPSTR,LPTSTR,LPWSTR等类型,LP含义即是长指针(long pointer),T的含义与前述类似,取决于是否设置了字符集为Unicode,W的含义即宽字符。 也就是说,LPSTR等同于char*,设置了Unicode字符集时,LPTSTR等同于wchar_t*,否则等同于char*,而LPWSTR等同于wchar_t* 在中,定义了宏_T …
WebApr 12, 2024 · 类别 ctypes. c_char_p. 当 C char *数据类型指向以零结尾的字符串时,表示它。对于也可能指向二进制数据的通用字符指针,必须使用POINTER(c_char)。构造函数接受整数地址或字节对象。 类别 ctypes. c_double. 表示 C double数据类型。构造函数接受一个可选的 float 初始化器。 WebOr without special support from numpy: you could convert y pointer to a pointer to an array type: ap = ctypes.cast (y, ctypes.POINTER (ArrayType)) where ArrayType = ctypes.c_double * array_length and create numpy array from that: a = np.frombuffer (ap.contents).

WebFeb 14, 2024 · 1 Answer. c_char_p is a char*. POINTER (c_char_p) is a char**. Fix your .restype and you should be good. ctypes has a default behavior of converting a c_char_p to a Python byte string. Also, mydll.cCreateObject.argtypes = None is correct for no arguments. The existing definition states a void* is a required parameter. cross my body dress fashion novaWebYou can cast the result, but ctypes allows you to use an array in place of a pointer, directly. The issue is the byref in your code (which would be the equivalent of a pointer to a pointer): So instead of: cresult = (c_ulong * num) () err = … cross mug rug patternWebOct 31, 2012 · ctypes.c_char_p Represents the C char * datatype when it points to a zero-terminated string. For a general character pointer that may also point to binary data, POINTER (c_char) must be used.
