Ok, thanks. Are there known bugs in it? I tried the following simple case on OS X:
test.h:
#ifndef TEST_H_
#define TEST_H_
#include <sys/select.h>
struct foo {
struct timeval select_timeout;
};
typedef struct foo foo;
#endif /* TEST_H_ */
test.c:
#ifndef TEST_C_
#define TEST_C_
#include "test.h"
int
main()
{
foo* a;
a->select_timeout.tv_sec = 10;
return 0;
}
#endif /* TEST_C_ */
I've added "." and "/usr/include" to the paths for the project. However I'm seeing an error on tv_sec: field could not be resolved.
Most likely /usr/include is not a correct include path for the compiler libraries, but I don't know what other directories it's supposed to include on OS X.
Hmm, well /usr/include is certainly the location of sys/select.h. I'm not sure what other compiler libraries might be involved, since this is presumably being analyzed before any linking is done.
It looks like select.h defines __need_struct_timeval and then includes <sys/_structs.h>. Then _structs.h defines struct timeval if __need_struct_timeval is defined. However when I open _structs.h the relevent section of code appears grey, so presumably the parser doesn't think this macro is set. It seems pretty simple, so it's strange that it doesn't work.
