annotate close.cpp @ 412:223eda8408e1 api-inversion

Fix the last compiler warning.

Bah.  A 26-line comment to explain a one-line change will not do any
good for the code deletion metric of productivity.  However, I have
learnt something today: specifically, the arithmetic type conversion
rules in C.  Wow.  I had been beginning to think that C programming
wasn't so bad after all: simple, clean semantics, and very little going
on under the hood; nothing there to help the programmer, but nothing
much to actively get in the way.  And then I spend an hour on this.

#include "audioDB.h"
extern "C" {
#include "audioDB_API.h"
#include "audioDB-internals.h"
}

void audiodb_close(adb_t *adb) {
  free(adb->path);
  free(adb->header);
  delete adb->keys;
  close(adb->fd);
  free(adb);
}
