If not, Then you can take a look here: https://github.com/freebsd/freebsd/blob/master/lib/msun/arm/fenv.c >> >> >> > --joel >> > >> > On Mon, Jul 1, 2019, 5:54 AM Vaibhav Gupta <vaibhavgupt...@gmail.com> >> > wrote: >> >> >> >> Hello, >> >> I am reading about memcpy to write it for newlib. >> >> Should I also write wmemcpy along with it? >> >> https://pubs.opengroup.org/onlinepubs/009695399/functions/wmemcpy.html >> >> . >> >> Regarding ndbm reference.
