Age	Commit message (Collapse)	Author	Lines
2013-09-20	correct the sysconf value for RTSIG_MAX	Rich Felker	-1/+2
	this is the number of realtime signals available, not the maximum signal number or total number of signals.
2013-09-15	support configurable page size on mips, powerpc and microblaze	Szabolcs Nagy	-6/+9
	PAGE_SIZE was hardcoded to 4096, which is historically what most systems use, but on several archs it is a kernel config parameter, user space can only know it at execution time from the aux vector. PAGE_SIZE and PAGESIZE are not defined on archs where page size is a runtime parameter, applications should use sysconf(_SC_PAGE_SIZE) to query it. Internally libc code defines PAGE_SIZE to libc.page_size, which is set to aux[AT_PAGESZ] in __init_libc and early in __dynlink as well. (Note that libc.page_size can be accessed without GOT, ie. before relocations are done) Some fpathconf settings are hardcoded to 4096, these should be actually queried from the filesystem using statfs.
2013-09-14	fix overflow in sysconf for _SC_MQ_PRIO_MAX	Rich Felker	-1/+2
	the value of MQ_PRIO_MAX does not fit, so it needs to use OFLOW.
2013-07-27	a few more fixes for unistd/sysconf feature reporting	Rich Felker	-7/+7

2013-07-26	report presence of ADV and MSG options in unistd.h and sysconf	Rich Felker	-2/+2

2013-07-26	report that posix_spawn is supported in unistd.h and sysconf	Rich Felker	-1/+1

2013-06-26	document in sysconf and unistd.h that per-thread cpu clocks exist	Rich Felker	-1/+1

2012-11-11	report support of TPS option in unistd.h and sysconf	Rich Felker	-2/+2
	also update another newish feature in sysconf, stackaddr
2012-05-13	let sysconf accurately report # of cpus available	Rich Felker	-2/+10
	i've been trying out openmp and it seems like it won't be much use without this...
2012-04-21	fix broken sysconf when correct value is -1	Rich Felker	-1/+1
	this caused glib to try to allocate >2gb for getpwnam_r, and probably numerous other problems.
2012-03-22	sysconf support for dynamic limits (open files and processes)	Rich Felker	-2/+9

2011-10-03	sysconf for PTHREAD_KEYS_MAX	Rich Felker	-1/+1

2011-08-16	in pathconf, -1, not 0, means unsupported.. syncio presumably works, too.	Rich Felker	-3/+3

2011-08-16	fix bogus pathconf result for file size bits	Rich Felker	-1/+1

2011-06-07	define MQ_PRIO_MAX	Rich Felker	-1/+1

2011-04-08	better fix sysconf pthread stack min	Rich Felker	-1/+1

2011-04-08	consistency with pthread stack min in limits.h	Rich Felker	-1/+1

2011-03-10	fix sem_open and sem_close to obey posix semantics	Rich Felker	-5/+5
	multiple opens of the same named semaphore must return the same pointer, and only the last close can unmap it. thus the ugly global state keeping track of mappings. the maximum number of distinct named semaphores that can be opened is limited sufficiently small that the linear searches take trivial time, especially compared to the syscall overhead of these functions.
2011-02-14	put confstr.c with the other conf functions	Rich Felker	-0/+17

2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	-0/+263
