I have a nested C struct (size is very large) and bytes

// In C:
struct example1 {
  int val1;
  int val2;
  int val3;
  int val4; 
  char c1;
  char c2;
  enum example2 e1;
  union example3 u1;
  struct example4 s1;
  ...
  ....
  ....
};

# In python
example1_bytes = b'\x08\x09\x0a\x0b...........'

How to map the bytes to C struct and access the member?

If you need to map those bytes in python, you can use struct.unpack()

The official Python Documentation will tell you how to write the format argument to map C types.

Example:

import struct
mapped_bytes = struct.unpack(">ii", example_bytes)
