These two macros are used to simplify the declaration of C-linkage code.
|
|
Rather than worry about preprocessor directives similar to
|
|
\code
|
|
#ifdef __cplusplus
|
|
extern "C" {
|
|
#endif
|
|
|
|
int foobar(void);
|
|
|
|
#ifdef __cplusplus
|
|
}
|
|
#endif
|
|
\endcode
|
|
you simply need to use the _BEGIN_C_DECL and _END_C_DECL macros instead.
|
|
|
|
\code
|
|
#include "lub/c_decl.h"
|
|
_BEGIN_C_DECL
|
|
|
|
int foobar(void);
|
|
|
|
_END_C_DECL
|
|
\endcode
|
