2012-11-11debloat src/thread tree but putting lots of junk in one fileRich Felker-7/+0
POSIX includes mostly-useless attribute-get functions for each attribute-set function, presumably out of some object-oriented dogmatism. the get functions are not useful with the simple idiomatic usage of attributes. there are of course possible valid uses of them (like writing wrappers for pthread init functions that perform special actions on the presence of certain attributes), but considering how tiny these functions are anyway, little is lost by putting them all in one file, and some build-time cost and archive-file-size benefits are achieved.
2012-11-11add support for thread scheduling (POSIX TPS option)Rich Felker-1/+1
linux's sched_* syscalls actually implement the TPS (thread scheduling) functionality, not the PS (process scheduling) functionality which the sched_* functions are supposed to have. omitting support for the PS option (and having the sched_* interfaces fail with ENOSYS rather than omitting them, since some broken software assumes they exist) seems to be the only conforming way to do this on linux.
2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker-1/+1
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2011-03-11implement dummy pthread_attr_[gs]etschedparam functionsRich Felker-0/+7
for some reason these functions are not shaded by the PS/TPS option in POSIX, so presumably they are mandatory, even though the functionality they offer is optional. for now, provide them in case any programs depend on their existence, but disallow any priority except the default.
