struct - Using one typedef to use on two different data types in C? -


if have struct below, can use void ** pointer if don't know type of object point to? 

typedef struct {    ... many other things defined here     void ** pointer;  };

if pointer array can either int or struct, possible encapsulate both in single typedef above? best solution can think of making 2 different typedefs, each accommodate either possibility:

typedef struct {    ... many other things defined here     struct ** pointer_struct;     int ** pointer_int;  };  typedef struct b {    ... same many other things defined here     int ** pointer_int;  };

or single struct accommodate both possibility either pointer_int or pointer_struct null: 

typedef struct {    ... many other things defined here     struct ** pointer_struct;     int ** pointer_int;  } ;

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
