source: roaraudio/roard/roard.c @ 1493:405133c68d28

Last change on this file since 1493:405133c68d28 was 1486:b283d24f34ef, checked in by phi, 15 years ago

done a lot checks for target capabilities, check for: ROAR_HAVE_UNIX, ROAR_HAVE_IO_POSIX, ROAR_HAVE_SETUID, ROAR_HAVE_SETGID, ROAR_HAVE_CHROOT, ROAR_HAVE_FORK, ROAR_HAVE_NICE, ROAR_HAVE_GETSERVBYNAME; also updated signal interface becasue current one only works on POSIX systems
