Good evening list,
eCos sys/select.h has an all-developing #if !defined(_POSIX_SOURCE); if
it is defined, there are no (proto)types for fd_set and friends or select().
If I read the Linux man page, the select types (fd_set) and prototypes
are defined from Posix in sys/select.h, and from sys/time.h,
sys/types.h, unistd.h according to earlier standards. So it would seem
incompatible (at least) that eCos only provides these (proto)types
ifndef _POSIX_SOURCE?
On the other hand, Linux stdio.h has conditional prototypes for fileno()
and fdopen() in stdio.h that depend on a defined _POSIX_SOURCE. eCos has
no conditions on providing these.
I need to compile my application for both Linux and eCos. Now, if I
define _POSIX_SOURCE, I have fileno and fdopen under Linux, but no
select and fd_set under eCos. If I don't define _POSIX_SOURCE, I have
select and fd_set under eCos but no fileno and fdopen under Linux.
Shouldn't eCos define fd_set and select() (also) if _POSIX_SOURCE? And
maybe, shouldn't eCos make providing fileno/fdopen depend on #ifdef
_POSIX_SOURCE?
