Synonym of System v interface definition

The System V Interface Definition (or SVID) is a standard which describes the AT&T UNIX System V behavior, including that of system calls, C libraries, available programs and devices. While it was not the first attempt at a standardizations document (the industry trade association /usr/group published a standard in 1984 based on System III with a few system call additions from BSD), it was an important effort of early standardization of UNIX in a period when UNIX variants were multiplying rapidly and portability was problematic at best. By 1986, AT&T required conformance with SVID issue 2 if vendors were to actually brand their products "System V R3". By the 1990s, however, its importance was largely eclipsed by POSIX and the Single UNIX Specification, which were based in part upon the SVID. Part of the reason for this was undoubtedly their vendor-independent approach (see Unix wars).

System V Interface Definition(SVID、System V インターフェイス仕様）は、AT&TのUNIX System Vの動作を規定した標準規格である。システムコール、C ライブラリ、その他のプログラムやデバイスを規定している。

System V Interface Definition (SVID) je standard, který popisuje AT&T UNIX System V jako jsou systémová volání, standardní knihovnu jazyka C, nutné programy a zarízení. Jedná se o duležitý krok standardizace UNIXu. Význam tohoto standardu byl zastínen vznikem standardu POSIX a Single UNIX Specification, které byly zcásti na SVID založeny.
