2 @appendix Contributors to the GNU C Library
4 The GNU C library was written originally by Roland McGrath, and is
5 currently maintained by Ulrich Drepper. Some parts of the library were
6 contributed or worked on by other people.
10 The @code{getopt} function and related code were written by
11 Richard Stallman, @w{David J.} MacKenzie, and @w{Roland McGrath}.
14 The merge sort function @code{qsort} was written by Michael J. Haertel.
17 The quick sort function used as a fallback by @code{qsort} was written
18 by Douglas C. Schmidt.
21 The memory allocation functions @code{malloc}, @code{realloc} and
22 @code{free} and related code were written by Michael J. Haertel,
23 @w{Wolfram Gloger}, and @w{Doug Lea}.
26 Fast implementations of many of the string functions (@code{memcpy},
27 @code{strlen}, etc.) were written by Torbj@"orn Granlund.
30 The @file{tar.h} header file was written by David J. MacKenzie.
33 The port to the MIPS DECStation running Ultrix 4
34 (@code{mips-dec-ultrix4})
35 was contributed by Brendan Kehoe and Ian Lance Taylor.
38 The DES encryption function @code{crypt} and related functions were
39 contributed by Michael Glad.
42 The @code{ftw} and @code{nftw} functions were contributed by Ulrich Drepper.
45 The startup code to support SunOS shared libraries was contributed by
49 The @code{mktime} function was contributed by Paul Eggert.
52 The port to the Sequent Symmetry running Dynix version 3
53 (@code{i386-sequent-bsd}) was contributed by Jason Merrill.
56 The timezone support code is derived from the public-domain timezone
57 package by Arthur David Olson and his many contributors.
60 The port to the DEC Alpha running OSF/1 (@code{alpha-dec-osf1}) was
61 contributed by Brendan Kehoe, using some code written by Roland McGrath.
64 The port to SGI machines running Irix 4 (@code{mips-sgi-irix4}) was
65 contributed by Tom Quinn.
68 The port of the Mach and Hurd code to the MIPS architecture
69 (@code{mips-@var{anything}-gnu}) was contributed by Kazumoto Kojima.
72 The floating-point printing function used by @code{printf} and friends
73 and the floating-point reading function used by @code{scanf},
74 @code{strtod} and friends were written by Ulrich Drepper. The
75 multi-precision integer functions used in those functions are taken from
76 GNU MP, which was contributed by Torbj@"orn Granlund.
79 The internationalization support in the library, and the support
80 programs @code{locale} and @code{localedef}, were written by Ulrich
81 Drepper. Ulrich Drepper adapted the support code for message catalogs
82 (@file{libintl.h}, etc.) from the GNU @code{gettext} package, which he
83 also wrote. He also contributed the @code{catgets} support and the
84 entire suite of multi-byte and wide-character support functions
85 (@file{wctype.h}, @file{wchar.h}, etc.).
88 The implementations of the @file{nsswitch.conf} mechanism and the files
89 and DNS backends for it were designed and written by Ulrich Drepper and
90 Roland McGrath, based on a backend interface defined by Peter Eriksson.
93 The port to Linux i386/ELF (@code{i386-@var{anything}-linux}) was
94 contributed by Ulrich Drepper, based in large part on work done in
95 Hongjiu Lu's Linux version of the GNU C Library.
98 The port to Linux/m68k (@code{m68k-@var{anything}-linux}) was
99 contributed by Andreas Schwab.
102 The ports to Linux/ARM (@code{arm-@var{ANYTHING}-linuxaout}) and ARM
103 standalone (@code{arm-@var{ANYTHING}-none}), as well as parts of the
104 IPv6 support code, were contributed by Philip Blundell.
107 Richard Henderson contributed the ELF dynamic linking code and other
108 support for the Alpha processor.
111 David Mosberger-Tang contributed the port to Linux/Alpha
112 (@code{alpha-@var{anything}-linux}).
115 The port to Linux on PowerPC (@code{powerpc-@var{anything}-linux})
116 was contributed by Geoffrey Keating.
119 Miles Bader wrote the argp argument-parsing package, and the argz/envz
123 Stephen R. van den Berg contributed a highly-optimized @code{strstr} function.
126 Ulrich Drepper contributed the @code{hsearch} and @code{drand48}
127 families of functions; reentrant @samp{@dots{}@code{_r}} versions of the
128 @code{random} family; System V shared memory and IPC support code; and
129 several highly-optimized string functions for i@var{x}86 processors.
132 The math functions are taken from @code{fdlibm-5.1} by Sun
133 Microsystems, as modified by J.T. Conklin, Ian Lance Taylor,
134 Ulrich Drepper, Andreas Schwab, and Roland McGrath.
137 The @code{libio} library used to implement @code{stdio} functions on
138 some platforms was written by Per Bothner and modified by Ulrich Drepper.
141 Eric Youngdale and Ulrich Drepper implemented versioning of objects on
145 Thorsten Kukuk provided an implementation for NIS (YP) and NIS+,
146 securelevel 0, 1 and 2.
149 Andreas Jaeger provided a test suite for the math library.
152 Mark Kettenis implemented the utmpx interface and an utmp daemon.
155 Ulrich Drepper added character conversion functions (@code{iconv}).
158 Thorsten Kukuk provided an implementation for a caching daemon for NSS
162 Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
165 Mark Kettenis provided a Hesiod NSS module.
168 The Internet-related code (most of the @file{inet} subdirectory) and
169 several other miscellaneous functions and header files have been
170 included from 4.4 BSD with little or no modification.
