| 2024年02月08日 | fix erroneous feature test macro check for ppoll | Rich Felker | -2/+2 |
|
commit f247462b0831cbf163e976ee9a909748c674b88b incorrectly hid ppoll
in the presence of _GNU_SOURCE due to an oversight that defining
_BSD_SOURCE does not implicitly define _GNU_SOURCE. at present,
headers still have to explicitly check for each feature profile level;
this may be changed at some point in the future via features.h, but
has not been changed yet.

| 2024年01月21日 | expose ppoll in default feature profile | Rich Felker | -2/+2 |
|
the ppoll function has been accepted as a future part of the standard
as the outcome of Austin Group tracker issue 1263. at some point it
should be exposed unconditionally, but for now, expose it in the
default feature profile.

| 2019年10月28日 | add time64 symbol name redirects to public headers, under arch control | Rich Felker | -0/+6 |
|
a _REDIR_TIME64 macro is introduced, which the arch's alltypes.h is
expected to define, to control redirection of symbol names for
interfaces that involve time_t and derived types. this ensures that
object files will only be linked to libc interfaces matching the ABI
whose headers they were compiled against.
along with time32 compat shims, which will be introduced separately,
the redirection also makes it possible for a single libc (static or
shared) to be used with object files produced with either the old
(32-bit time_t) headers or the new ones after 64-bit time_t switchover
takes place. mixing of such object files (or shared libraries) in the
same program will also be possible, but must be done with care; ABI
between libc and a consumer of the libc interfaces is guaranteed to
match by the the symbol name redirection, but pairwise ABI between
consumers of libc that define interfaces between each other in terms
of time_t is not guaranteed to match.
this change adds a dependency on an additional "GNU C" feature to the
public headers for existing 32-bit archs, which is generally
undesirable; however, the feature is one which glibc has depended on
for a long time, and thus which any viable alternative compiler is
going to need to provide. 64-bit archs are not affected, nor will
future 32-bit archs be, regardless of whether they are "new" on the
kernel side (e.g. riscv32) or just newly-added (e.g. a new sparc or
xtensa port). the same applies to newly-added ABIs for existing
machine-level archs.

| 2016年07月03日 | make brace placement in public header struct definitions consistent | Rich Felker | -2/+1 |
|
placing the opening brace on the same line as the struct keyword/tag
is the style I prefer and seems to be the prevailing practice in more
recent additions.
these changes were generated by the command:
find include/ arch/*/bits -name '*.h' \
-exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} +
and subsequently checked by hand to ensure that the regex did not pick
up any false positives.

| 2015年03月04日 | fix preprocessor error introduced in poll.h in last commit | Rich Felker | -1/+1 |
|
| 2015年03月04日 | fix POLLWRNORM and POLLWRBAND on mips | Trutz Behn | -0/+6 |
|
these macros have the same distinct definition on blackfin, frv, m68k,
mips, sparc and xtensa kernels. POLLMSG and POLLRDHUP additionally
differ on sparc.
|
| 2012年12月26日 | add linux extension POLLRDHUP to poll.h | Rich Felker | -0/+1 |
|
the POLL prefix is in the reserved namespace for poll.h, so no feature
test macro checks are needed.
|
| 2012年09月09日 | fix typo introduced in poll.h | Rich Felker | -1/+1 |
|
| 2012年09月09日 | add linux ppoll syscall wrapper | Rich Felker | -0/+10 |
|
| 2012年09月01日 | fix wrong type for poll.h nfds_t | Rich Felker | -1/+1 |
|
this should not break anything since the type should never be used
except as the argument type for poll.

| 2011年02月12日 | initial check-in, version 0.5.0 v0.5.0 | Rich Felker | -0/+35 |
