2016-06-15sysconf: Support _SC_(AV)?PHYS_PAGES.Nicolas Cavallari
Do it by following the trail of the existing commented code, which implemented it by calling get_phys_pages() and get_avphys_pages(). This patch implements these two functions, which are also glibc extensions. Some program/libraries (e.g. libuv) assumes that sysconf(_SC_PHYS_PAGES) works on linux and never check for -1, thus they report an insane amount of memory.

This matches a similar change made to glibc. No functional changes here. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-06-15sysconf.c: the clock_getres function is good for NPTL as wellPeter S. Mazinger
Even if glibc reuses the syscall (bloat), we can reuse the function. Make sure, that we use it only if it is provided by the syscall and the function is really around (UCLIBC_HAS_REALTIME disables it), else we get into a loop. Signed-off-by: Peter S.

2012-04-18sysconf: use getrlimit to determine ARG_MAXBernhard Reutner-Fischer
getrlimit previously was only called for NPTL (why?), fix that to be used everywhere. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2007-04-13Patch by Ricard Wanderlof <ricardw at axis dot com>:Peter Kjellerstedt
* Add configurable buffer sizes for getpwnam() and getgrnam(). The default buffer size is, as before, 256 (glibc seems to use 1024 by default).

2004-07-15Cleanup a few of the more egregiously broken sysconf values toEric Andersen
actually match reality. In particular, _SC_GETPW_R_SIZE_MAX and _SC_GETGR_R_SIZE_MAX were causing us problems with programs such as libglib, since they were always returning -1, which is a bit smaller than the actual passwd and group max buffer sizes. -Erik

static version. This will need further work later on, but should do the job for the time being,

generally be the truth...
2002-07-15Clean up CLK_TCK situation. clock() and sysconf() now use anManuel Novoa III
arch-specific constant value defined in bits/uClibc_clk_tck.h. Default is 100 (common/bits) but alpha uses 1024 following glibc. Override per arch as necessary.
2001-11-20Oops. Lets try that again.Eric Andersen
2001-11-20Can't use CLK_TCK in here since /usr/include/bits/time.h nowEric Andersen
defines that as __sysconf(_SC_CLK_TCK) causing infinite recursion. -Erik

2001-04-06Fix include/errno.h to not use kernel header, and instead use bits/errno.h.Eric Andersen
This required we use _LIBC instead of __LIBC__ to be consistent with glibc. This had some sideffects in sys/syscalls.h. While fixing things, I made everything use __set_errno() for (eventual) thread support. -Erik
