These web pages contain tables of interfaces defined in the Single UNIX Specification Version 3, complete with an indication of their availability in other related standards, such as UNIX 98, UNIX 95, the ISO POSIX-1 standard, the ISO POSIX-2 standard, the ISO C standard, SVID3 and 4.3BSD.

These are available as a single file in PDF. ( PDF viewers for 18 platforms are available from here ).

These tables are intended as a quick reference guide for programmers migrating or developing applications for the Single UNIX Specification Version 3. Products that certify to the Single UNIX Specification Version 3 may not provide all of the interfaces listed, depending on which feature groups are supported.

The System Interfaces are split into several tables and organized alphabetically:

· A - C · D - F · G - I · J - L · M · N - O · P · Q - R · S · T · U - V · W - Y

The Commands and Utilities are available as a single table: · Commands (A-Z)

The Headers are available as a single table: · Headers (A-Z)

The XCURSES interfaces are available as a single table: · Xcurses (A-Z)
