[go-nuts] How to access pointer to pointer in cgo

[Manohar Reddy]

These are the things I have in C.


IMAGE_OPTIONAL_HEADER *pe_optional(pe_ctx_t *ctx);

typedef struct {
  uint16_t Magic;
}IMAGE_OPTIONAL_HEADER_32;

typedef struct {
  uint16_t type;
  IMAGE_OPTIONAL_HEADER_32 *_32;
}IMAGE_OPTIONAL_HEADER;




In c language to access Magic variable, I did  this and it worked. 


IMAGE_OPTIONAL_HEADER *optional = pe_optional(&ctx);
printf(“%d \n”, optional->_32->Magic)


But how to access the same in golnag? I did


optional := pe_optional(&ctx);
fmt.Println(optional._type) // worked for me 
fmt.Println(optional._32.Magic) // did not work for me: HOW TO ACCESS MAGIC 
VARIABLE



Doubt is : how to do I access `Magic` variable in go?


Thanks
