If an interface is listed as "changed" (C), a brief description of differences between the SunOS release 4 and Solaris 7 file is provided.
If an interface is listed as "the same" (S), the Solaris 7 interface supports all features of the SunOS release 4 interface. In some cases the interface has been enhanced, but can be considered a complete superset of the SunOS release 4 interface.
If an interface is listed as "not available" (N), check the Notes section for information about its replacement.
For complete information on all Solaris 7 interfaces, see the man Pages(4): File Formats.
