intro -- introduction to the system libraries
This section provides an overview of the system libraries, their func-
tions, error returns and other common definitions and concepts. Most of
these functions are available from the standard C library, libc. Other
libraries, such as the math library, libm, must be indicated at compile
time with the -l option of the compiler.
The various system libraries supplied in NetBSD (followed by the linker
The abstract syntax notation (ASN) library provides routines
for the specification of abstract data types.
Block-sorting compressor library providing routines for fast
and efficient compression.
libc (-lc) The standard C library. When using the C compiler cc(1), it
is not necessary to supply the linker flag -lc for these
functions. There are several subsystems included inside
standard I/O routines
character tests and character operators
encryption and hash routines
see md4(3) and md5(3).
see mpool(3) and malloc(3)
The common error description library. See com_err(3).
Functions which are obsolete but are available for compati-
bility with 4.3BSD. In particular, a number of system call
interfaces provided in previous releases of BSD have been
included for source code compatibility. Use of these rou-
tines should, for the most part, be avoided. The manual page
entry for each compatibility routine indicates the proper
interface to use.
The crypt library. See crypt(3).
The OpenSSL cryptographic library. See crypto(7).
libcurses (-lcurses -lterminfo)
Terminal independent screen management routines for two
dimensional non-bitmap display terminals. See curses(3).
The OpenSSL cryptographic library for the DES algorithms.
The device-mapper driver access library used for communica-
tion with kernel driver dm(4) and for lvm(8) subsystem.
The command-line editor or editline library. The editline
library provides generic editing and history functions. See
The curses form library provides a terminal-independent form
system using the curses library. The form library provides
facilities for defining forms on terminals. See forms(3).
The Generic Security Services (GSS) API library. This
library provides verification services to applications and
usually sits above the cryptographic libraries.
The Hesiod library. This library provides routines for per-
forming lookups of Hesiod information, which is stored as
text records in the Domain Name Service. See hesiod(3).
The Heimdal Kerberos 5 authentication/authorisation database
The internationalized message handling library. See
The IPsec policy control library. See ipsec_set_policy(3)
The Kerberos 5 administration client library.
The Kerberos 5 administration server library. See
The Kerberos IV AFS library. See kafs(3).
The Kerberos IV authentication/authorisation database access
The Kerberos IV library.
The Kerberos 5 library. See krb5(3).
Kerberos IV encrypted stream library.
Kernel data access library. See kvm(3).
libl (-ll) The library for lex(1).
libm (-lm) The math library. See math(3).
The curses menu library. See menus(3).
NetBSD Virtualization API. See libnvmm(3).
Open Sound System compatibility library. See ossaudio(3).
The curses panel library. See panel(3).
The packet capture library. See pcap(3).
The PCI bus access library. See pci(3).
The POSIX compatibility library provides a compatibility
interface for POSIX functions which differ from the standard
BSD interfaces. See chown(2) and rename(2).
The DNS resolver library.
Remote magnetic tape library. See rmtops(3).
A library containing compatibility functions used by Ker-
beros. It implements functionality required by the Kerberos
implementation not implemented in the standard NetBSD
The Remote Procedure Call (RPC) services library. See
The S/Key one-time password library. See skey(3).
The secure sockets layer (SSL) library. See ssl(7).
The telnet library.
The terminal-independent operation library. See terminfo(3).
The Universal Serial Bus (USB) Human Interface Devices access
library. See libusbhid(3).
The system utilities library. See util(3).
The TCP wrappers library. See hosts_access(3).
liby (-ly) The library for yacc(1).
libz (-lz) General-purpose compression library. See zlib(3).
