If an interface is listed as "changed" (C), a brief description of differences between the SunOS 4.x 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 4.x interface. In some cases the interface has been enhanced, but can be considered a complete superset of the SunOS 4.x 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.
