SET_VERSION(2)
NAME
set_version, get_version − set/get system version (obsolete)
USAGE
set_version(string) char *string;
get_version (cp) char cp[16];
DESCRIPTION
These calls are obsolete. We include them in this release for compatability only. However, we do not encourage their continued use, and we cannot promise their continued support.
The DOMAIN/IX function set_version allows programs to specify the version of DOMAIN/IX — AT&T UNIX System V or Berkeley 4.2 UNIX — that will be used to define arguments and semantics for certain system and library functions. Valid string arguments are “bell” and “berkeley”. The default version is “bell”. The selected version is inherited across program invocation, exec(2), and by forked children.
The DOMAIN/IX function get_version returns a string identifying the version of UNIX (Bell UNIX System V or Berkeley UNIX) currently interpreting arguments and semantics for certain system and library functions. It returns either “bell” or “berkeley”.
