_XPG4 The _XPG4 feature test macro is defined automatically if the programmer has
requested the XPG4 namespace (that is, defined
_XOPEN_SOURCE, but not
some other conflicting namespace such as
_XPG3).
_SVID2 The _SVID2 macro can be defined when using the compatibility mode com-
piler to obtain SVID2 function return types in the HP-UX namespace. The
default return types of many functions have since been changed in the HP-UX
operating system to align with the ANSI-C, POSIX, X/Open, and OSF stan-
dards. Use of this macro is strongly discouraged as this functionality will be
removed in a future release of HP-UX.
_SVID3 The SVID3 macro can be defined to obtain SVID3 function prototypes. The
compiler flag, -D_SVID3, needs to be defined to indicate that an application
is written to meet SVID3 requirements. At the time the function prototypes
were introduced in ANSI C, the functions exposed by this flag were only
defined in SVID3.
