musl/src/thread/pthread_attr_getschedpolicy.c, branch v1.1.19 musl - an implementation of the standard library for Linux-based systems debloat src/thread tree but putting lots of junk in one file 2012-11-11T21:08:38+00:00 Rich Felker dalias@aerifal.cx 2012-11-11T21:08:38+00:00 c4a35f8c2a4b1a7e62a4b9e5b2748fb4fbcace79 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.

add support for thread scheduling (POSIX TPS option) 2012-11-11T20:38:04+00:00 Rich Felker dalias@aerifal.cx 2012-11-11T20:38:04+00:00 1e21e78bf7a5c24c217446d8760be7b7188711c2 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.
