NAME    [Toc]    [Back]

     intro - introduction to the system libraries

DESCRIPTION    [Toc]    [Back]

     This section provides an overview of the system libraries, their functions,
 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
     flags) are:

     libasn1 (-lasn1)
                 The abstract syntax notation (ASN) library provides routines
                 for the specification of abstract data types.

     libbz2 (-lbz2)
                 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
                         see stdio(3)

                 database routines
                         see db(3)

                 bit operators
                         see bit_string(3)

                 string operators
                         see string(3)

                 character tests and character operators

                 encryption and hash routines
                         see md4(3) and md5(3).

                 storage allocation
                         see mpool(3) and malloc(3)

                 time functions
                         see time(3)

                 signal handling
                         see signal(3)

     libcdk (-lcdk)
                 Curses development kit (CDK) library.  See cdk(3).

                 The common error description library.  See com_err(3).

     libcompat (-lcompat)
                 Functions which are obsolete but are available for compatibility
 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 routines
 should, for the most part, be avoided.  The manual page
                 entry for each compatibility routine indicates the proper
                 interface to use.

     libcrypt (-lcrypt)
                 The crypt library.  See crypt(3).

                 The OpenSSL cryptographic library.  See crypto(3).

     libcrypto_idea (-lcrypto_idea)
                 The OpenSSL cryptographic library routines for the IDEA algorithm.
  This algorithm is separated from libcrypto since the
                 IDEA algorithm is protected by patents and its use is

     libcrypto_rc5 (-lcrypto_rc5)
                 The OpenSSL cryptographic library routines for the RC5 algorithm.
  This algorithm is separated from libcrypto since the
                 RC5 algorithm is protected by patents and its use is

     libcurses (-lcurses -ltermcap)
                 Terminal independent screen management routines for two
                 dimensional non-bitmap display terminals.  See curses(3).

     libdes (-ldes)
                 The OpenSSL cryptographic library for the DES algorithms.
                 See des(3).

     libedit (-ledit)
                 The command-line editor or editline library.  The editline
                 library provides generic editing and history functions.  See

     libform (-lform)
                 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).

     libgssapi (-lgssapi)
