4984 :: minizip bindings

• mantielero (orginal) [2019-07-01T16:48:11+02:00] view original

  As I mentioned in some posts before, I am trying to create some bindings to a C library (for the sake of learning). I am not very familiar with C/C++, so you might expect many trivial questions. I will try to keep all my questions in this thread.

  From other posts, it looks like a sensible thing to do is to use nimterop over the header.

  When I run:

  toast -p -r zlib-1.2.11/contrib/minizip/unzip.h > unzip_full.h

  I get something like:

  #define _unz64_H
  extern "C" {
  #define Z_BZIP2ED 12
  typedef voidp unzFile;
  #define UNZ_OK (0)
  #define UNZ_END_OF_LIST_OF_FILE (-100)
  Run

  I don't know why I am getting the second line extern "C" {. The header used contains:

  #ifdef __cplusplus
  extern "C" {
  #endif
  Run

  If I don't have defined __cplusplus, I understand that the line shouldn't be exported. What am I missing?
