GNU Info (libc.info)ContributorsContributors to the GNU C Library ********************************* The GNU C library was written originally by Roland McGrath, and is currently maintained by Ulrich Drepper. Some parts of the library were contributed or worked on by other people. * The `getopt' function and related code was written by Richard Stallman, David J. MacKenzie, and Roland McGrath. * The merge sort function `qsort' was written by Michael J. Haertel. * The quick sort function used as a fallback by `qsort' was written by Douglas C. Schmidt. * The memory allocation functions `malloc', `realloc' and `free' and related code were written by Michael J. Haertel, Wolfram Gloger, and Doug Lea. * Fast implementations of many of the string functions (`memcpy', `strlen', etc.) were written by Torbjo"rn Granlund. * The `tar.h' header file was written by David J. MacKenzie. * The port to the MIPS DECStation running Ultrix 4 (`mips-dec-ultrix4') was contributed by Brendan Kehoe and Ian Lance Taylor. * The DES encryption function `crypt' and related functions were contributed by Michael Glad. * The `ftw' and `nftw' functions were contributed by Ulrich Drepper. * The startup code to support SunOS shared libraries was contributed by Tom Quinn. * The `mktime' function was contributed by Paul Eggert. * The port to the Sequent Symmetry running Dynix version 3 (`i386-sequent-bsd') was contributed by Jason Merrill. * The timezone support code is derived from the public-domain timezone package by Arthur David Olson and his many contributors. * The port to the DEC Alpha running OSF/1 (`alpha-dec-osf1') was contributed by Brendan Kehoe, using some code written by Roland McGrath. * The port to SGI machines running Irix 4 (`mips-sgi-irix4') was contributed by Tom Quinn. * The port of the Mach and Hurd code to the MIPS architecture (`mips-ANYTHING-gnu') was contributed by Kazumoto Kojima. * The floating-point printing function used by `printf' and friends and the floating-point reading function used by `scanf', `strtod' and friends were written by Ulrich Drepper. The multi-precision integer functions used in those functions are taken from GNU MP, which was contributed by Torbjo"rn Granlund. * The internationalization support in the library, and the support programs `locale' and `localedef', were written by Ulrich Drepper. Ulrich Drepper adapted the support code for message catalogs (`libintl.h', etc.) from the GNU `gettext' package, which he also wrote. He also contributed the `catgets' support and the entire suite of multi-byte and wide-character support functions (`wctype.h', `wchar.h', etc.). * The implementations of the `nsswitch.conf' mechanism and the files and DNS backends for it were designed and written by Ulrich Drepper and Roland McGrath, based on a backend interface defined by Peter Eriksson. * The port to Linux i386/ELF (`i386-ANYTHING-linux') was contributed by Ulrich Drepper, based in large part on work done in Hongjiu Lu's Linux version of the GNU C Library. * The port to Linux/m68k (`m68k-ANYTHING-linux') was contributed by Andreas Schwab. * The ports to Linux/ARM (`arm-ANYTHING-linuxaout') and ARM standalone (`arm-ANYTHING-none'), as well as parts of the IPv6 support code, were contributed by Philip Blundell. * Richard Henderson contributed the ELF dynamic linking code and other support for the Alpha processor. * David Mosberger-Tang contributed the port to Linux/Alpha (`alpha-ANYTHING-linux'). * The port to Linux on PowerPC (`powerpc-ANYTHING-linux') was contributed by Geoffrey Keating. * Miles Bader wrote the argp argument-parsing package, and the argz/envz interfaces. * Stephen R. van den Berg contributed a highly-optimized `strstr' function. * Ulrich Drepper contributed the `hsearch' and `drand48' families of functions; reentrant `...`_r'' versions of the `random' family; System V shared memory and IPC support code; and several highly-optimized string functions for iX86 processors. * The math functions are taken from `fdlibm-5.1' by Sun Microsystems, as modified by J.T. Conklin, Ian Lance Taylor, Ulrich Drepper, Andreas Schwab, and Roland McGrath. * The `libio' library used to implement `stdio' functions on some platforms was written by Per Bothner and modified by Ulrich Drepper. * Eric Youngdale and Ulrich Drepper implemented versioning of objects on symbol level. * Thorsten Kukuk provided an implementation for NIS (YP) and NIS+, securelevel 0, 1 and 2. * Andreas Jaeger provided a test suite for the math library. * Mark Kettenis implemented the utmpx interface and an utmp daemon. * Ulrich Drepper added character conversion functions (`iconv'). * Thorsten Kukuk provided an implementation for a caching daemon for NSS (nscd). * Tim Waugh provided an implementation of the POSIX.2 wordexp function family. * Mark Kettenis provided a Hesiod NSS module. * The Internet-related code (most of the `inet' subdirectory) and several other miscellaneous functions and header files have been included from 4.4 BSD with little or no modification.
