Issue ID: 24417
Summary: core.sys.posix.sys.select: fds_bits named __fds_bits
on FreeBSD
Product: D
Version: D2
Hardware: All
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P1
Component: druntime
Assignee: nobody at puremagic.com
Reporter: issues.dlang at jmdavisProg.com
It looks like on FreeBSD (and on the BSDs in general) fds_bits is declared
using a #define - e.g.
---
typedef struct fd_set {
__fd_mask __fds_bits[_howmany(FD_SETSIZE, _NFDBITS)];
} fd_set;
#if __BSD_VISIBLE
#define fds_bits __fds_bits
#endif
---
rather than having the standard name used directly - probably due in part to
the quirks of C with typedef-ing structs and unions. But the standard name is
fds_bits, not __fds_bits, so either the field needs to be renamed to fds_bits,
or it needs to be aliased, otherwise the binding for fds_bits doesn't actually
exist.
