arm - Status of setcontext / getcontext in BSD and Linux -

-

i using setcontext / getcontext creating coroutines in c. current software implemented armv7 using linux 3.18 kernel. since these apis deprecated, couldn't find proper information regarding development status. have read reimplemented arm deprecated on x86 oses. however, can still find up-to-date man pages freebsd , linux. there aren't warnings or notices regarding use.

is reliable choice continue using them ? why still exists in libc ? status in linux kernel 4 ?

thanks
