chao an	c24dc389e4	sched/task: add kernel interface nxsched_* gettid/getpid/getppid ... add new interface to implement getpid()/gettid()/getppid() for kernel version. Signed-off-by: chao an <anchao@xiaomi.com>	2023-02-02 10:33:01 +08:00
Xiang Xiao	d9cfeb0bc3	sched: Don't forward gettid to getpid directly ... prepare to implement the right semantics: getpid should return the main thread id gettid should return the current thread id	2021-03-04 17:17:41 -06:00
Gregory Nutt	ebdfd16f0f	Move gettid() implementation to /libs/libc/unistd ... Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c. gettid() is a dumb wrapper around getpid(). It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid(). Instead, move gettid() in the C library where it calls the single sysgtem call, getpid(). Much cleaner.	2020-09-22 19:40:56 -07:00
