9 Functions in this library provide various facilities defined by System
10 V, ANSI C, POSIX, and so on. See standards(5). In addition, those
11 facilities previously defined in the internationalization and the wide-
12 character libraries are now defined in this library, as are the facili‐
13 ties previously defined in the multithreading libraries, libthread and
14 libpthread.

17 The shared object libc.so.1 provides the public interfaces defined
18 below. See Intro(3) for additional information on shared object inter‐
19 faces.

915 The synonyms compatibility library, c_synonyms.so.1, provides a mecha‐
916 nism to support old applications and libraries that were mistakenly
917 built using now-obsolete synonym symbols from libc.
918 Before the advent of direct binding (-B direct) libc provided many
921 functions with two names. For example, getpwent() and _getpwent().
922 These two names referred to exactly the same function in libc. The
923 leading-underscore symbol was intended to be used by system libraries
924 in order to avoid conflicting with an application that might define its
925 own version of getpwent() with completely different semantics. Stan‐
926 dard-conforming applications may not define and use function names with
927 leading underscores.
928 Solaris system libraries are now built with direct binding. This means
931 that a system library that calls getpwent() will bind directly to the
932 instance of getpwent() in libc, even if the application to which it is
933 linked defines a different getpwent() for its own use. The application
934 binds to its instance of getpwent() and there is no resulting conflict.
935 The direct binding mechanism is equally available to libraries not
936 delivered with Solaris.
937 As a result of this evolution, most of the leading-underscore synonym
940 symbols have been removed from libc. This means that applications that
941 call these now-obsolete function names will cease to work. They will
942 typically draw the error:
943 $ ./application
945 ld.so.1: fatal: relocation error: symbol _getpwent:
946 referenced symbol not found
947 Killed
948 All of the old leading-underscore symbols have been copied to the syn‐
953 onyms compatibility library. This library simply redirects the calls to
954 the non-underscore instances of the corresponding functions in libc.
955 Use it as a pre-loaded object:
956 $ LD_PRELOAD=c_synonyms.so.1 ./application
958 The synonyms compatibility library is intended neither to enable the
963 generation of applications that call the obsolete leading-underscore
964 synonym functions, nor to endorse this particular programming practice.
