Following up, I initially answered from my phone and didn't look at source. I am still on my phone but looked through the list and think the last four methods are probably the only ones currently supported. https://sourceware.org/git/?p=newlib-cygwin.git;a=tree;f=newlib/libc/string;h=ceeec602cdd0e6b5c6b002b741bda9b41da4e441;hb=HEAD POSIX support comes from a mix of RTEMS and newlib. That's key to this type of project. --joel > > > >> Thanks very much for your time! >> >> Sincerely, >> >> Matt >> >
