如何在Swift5上在macOS上使用libbsm/openbsm？

Question

我尝试在Swift5中使用libbsm/openbsm库和Xcode11。

为什么？我不能很好的AUDITPIPE_SET_PRESELECT_MODE。

我可以在Swift中使用libbsm/openbsm吗？

var mode = AUDITPIPE_PRESELECT_MODE_LOCAL // <- works very well
if ioctl(auditFD, AUDITPIPE_SET_PRESELECT_MODE, &mode) == -1 {
    return -1
}

我遇到了同样的问题，Swift无法导入这些复杂的宏。奎因“爱斯基摩人”指示我将它们声明为c常量。所以我在我的项目中的一个c文件中创建了它们。

在.h文件中，我执行了以下操作：

#include <stdio.h>
#include <bsm/libbsm.h>
#include <sys/ioctl.h>
#include <security/audit/audit_ioctl.h>


// -- Macros used for creating an auditpipe
extern unsigned long QAUDITPIPE_SET_PRESELECT_MODE;
extern unsigned long QAUDITPIPE_GET_QLIMIT_MAX;
extern unsigned long QAUDITPIPE_SET_QLIMIT;
extern unsigned long QAUDITPIPE_SET_PRESELECT_FLAGS;
extern unsigned long QAUDITPIPE_SET_PRESELECT_NAFLAGS;
// -- End auditpipe macros

在我的.c文件中，我有：

unsigned long QAUDITPIPE_SET_PRESELECT_MODE = AUDITPIPE_SET_PRESELECT_MODE;
unsigned long QAUDITPIPE_GET_QLIMIT_MAX = AUDITPIPE_GET_QLIMIT_MAX;
unsigned long QAUDITPIPE_SET_QLIMIT = AUDITPIPE_SET_QLIMIT;
unsigned long QAUDITPIPE_SET_PRESELECT_FLAGS = AUDITPIPE_SET_PRESELECT_FLAGS;
unsigned long QAUDITPIPE_SET_PRESELECT_NAFLAGS = AUDITPIPE_SET_PRESELECT_NAFLAGS;

所以现在我可以在我的Swift代码中使用QAUDITPIPE_SET_PRESELECT_MODE了。效果很好！
