NAME

libc - C library

DESCRIPTION

Functions in this library provide various facilities defined by System V, ANSI C, POSIX, and so on. See standards(5). In

addition, those facilities previously defined in the inter-

nationalization and the wide-character libraries are now

defined in this library, as are the facilities previously defined in the multithreading libraries, libthread and libpthread. INTERFACES

The shared object libc.so.1 provides the public interfaces

defined below. See Intro(3) for additional information on shared object interfaces.

bols from libc.

Before the advent of direct binding (-B direct) libc pro-

vided many functions with two names. For example,

getpwent() and _getpwent(). These two names referred to

exactly the same function in libc. The leading-underscore

symbol was intended to be used by system libraries in order to avoid conflicting with an application that might define its own version of getpwent() with completely different

semantics. Standard-conforming applications may not define

and use function names with leading underscores. Solaris system libraries are now built with direct binding. This means that a system library that calls getpwent() will

bind directly to the instance of getpwent() in libc, even if

the application to which it is linked defines a different

Interface Libraries libc(3LIB)

getpwent() for its own use. The application binds to its instance of getpwent() and there is no resulting conflict. The direct binding mechanism is equally available to libraries not delivered with Solaris.

As a result of this evolution, most of the leading-

underscore synonym symbols have been removed from libc.

This means that applications that call these now-obsolete

function names will cease to work. They will typically draw the error:

$ ./application

ld.so.1: fatal: relocation error: symbol _getpwent:

referenced symbol not found Killed

All of the old leading-underscore symbols have been copied

to the synonyms compatibility library. This library simply

redirects the calls to the non-underscore instances of the

corresponding functions in libc. Use it as a pre-loaded

object:

$ LD_PRELOAD=c_synonyms.so.1 ./application

The synonyms compatibility library is intended neither to enable the generation of applications that call the obsolete

leading-underscore synonym functions, nor to endorse this

particular programming practice.
