-.SH NAME
-libc \- overview of standard C libraries on Linux
-.SH DESCRIPTION
-The term "libc" is commonly used as a shorthand for
-the "standard C library",
-a library of standard functions that can be used by all C programs
-(and sometimes by programs in other languages).
-Because of some history (see below), use of the term "libc"
-to refer to the standard C library is somewhat ambiguous on Linux.
-.SS glibc
-By far the most widely used C library on Linux is the GNU C Library
-.UR http://www.gnu.org\:/software\:/libc/
-.UE ,
-often referred to as
-.IR glibc .
-This is the C library that is nowadays used in all
-major Linux distributions.
-It is also the C library whose details are documented
-in the relevant pages of the
-.I man-pages
-project (primarily in Section 3 of the manual).
-Documentation of glibc is also available in the glibc manual,
-available via the command
-.IR "info libc" .
-Release 1.0 of glibc was made in September 1992.
-(There were earlier 0.x releases.)
-The next major release of glibc was 2.0, at the beginning of 1997.
-
-The pathname
-.I /lib/libc.so.6
-(or something similar) is normally a symbolic link that
-points to the location of the glibc library,
-and executing this pathname will cause glibc to display
-various information about the version installed on your system.
-.SS Linux libc
-In the early to mid 1990s, there was for a while
-.IR "Linux libc" ,
-a fork of glibc 1.x created by Linux developers who felt that glibc
-development at the time was not sufficing for the needs of Linux.
-Often, this library was referred to (ambiguously) as just "libc".
-Linux libc released major versions 2, 3, 4, and 5
-(as well as many minor versions of those releases).
-For a while,
-Linux libc was the standard C library in many Linux distributions.
-
-However, notwithstanding the original motivations of the Linux libc effort,
-by the time glibc 2.0 was released (in 1997),
-it was clearly superior to Linux libc,
-and all major Linux distributions that had been using Linux libc
-soon switched back to glibc.
-Since this switch occurred long ago,
-.I man-pages
-no longer takes care to document Linux libc details.
-Nevertheless, the history is visible in vestiges of information
-about Linux libc that remain in some manual pages,
-in particular, references to
-.IR libc4
-and
-.IR libc5 .
-.SS Other C libraries
-There are various other less widely used C libraries for Linux.
-These libraries are generally smaller than glibc,
-both in terms of features and memory footprint,
-and often intended for building small binaries,
-perhaps targeted at development for embedded Linux systems.
-Among such libraries are
-.UR http://www.uclibc.org/
-.I uClibc
-.UE ,
-.UR http://www.fefe.de/dietlibc/
-.I dietlibc
-.UE ,
-and
-.UR http://www.musl-libc.org/
-.I "musl libc"
-.UE .
-Details of these libraries are covered by the
-.I man-pages
-project, where they are known.
