[Bug libc/11093] New: <poll.h> does not define POLL[RD|WR]* macros with _POSIX_C_SOURCE="200809L"

- Reply-to: sourceware-bugzilla at sourceware dot org
As of POSIX.1-2008, the <poll.h> header was moved completely to the base
specification [1]. Therefore, a definition of _POSIX_C_SOURCE to 200809L alone
should be enough to get all definitions in <poll.h> specified by POSIX.1-2008.
Currently, however, the POLLRDNORM, POLLRDBAND, POLLWRNORM and POLLWRBAND depend
on _XOPEN_SOURCE.
Test program:
#define _POSIX_C_SOURCE 200809L
#include <poll.h>
int main (void)
{
struct pollfd fds[] = {
{
.fd = 0,
.events = POLLIN | POLLRDNORM | POLLRDBAND
},
{
.fd = 1,
.events = POLLOUT | POLLWRNORM | POLLWRBAND
}
};
(void)fds;
}
