Just for fun I added this prototype to the code:
extern "C" int select(int, fd_set*, fd_set*, fd_set*, struct timeval*);
Now I get complaints from <sys/select.h> about duplicate definitions
of select() :o(
This indicates that sys/select.h should be wrapped in the extern "C".
Sounds like this got removed from a recent commit.
In general, all headers for C functions should look like:
#ifndef MY_HEADER
#define MY_HEADER
#include <blah.h>
#include ...
#ifdef __cplusplus
extern "C" {
#endif
void my_function();
#ifdef __cplusplus
}
#endif
#endif /* MY_HEADER */
