- iinnttrroo - introduction to the C libraries
-
- DDEESSCCRRIIPPTTIIOONN
- This section provides an overview of the C library functions, their error
- returns and other common definitions and concepts. Most of these func-
- tions are available from the C library, _l_i_b_c. Other libraries, such as
- the math library, _l_i_b_m, must be indicated at compile time with the --ll op-
- tion of the compiler.
-
- The various libraries (followed by the loader flag):
-
- libc(--ll_c) Standard C library functions. When using the C compiler
- cc(1), it is not necessary to supply the loader flag --ll_c for
- these functions. There are several `libraries' or groups of
- functions included inside of libc: the standard I/O rou-
- tines, database routines, bit operators, string operators,
- character tests and character operators, des encryption rou-
- tines, storage allocation, time functions, signal handling
- and more.
-
- libcurses( --ll_c_u_r_s_e_s --ll_t_e_r_m_c_a_p)
- Terminal independent screen management routines for two di-
- mensional non-bitmap display terminals. (See curses(3).)
-
- libcompat(--ll_c_o_m_p_a_t)
- 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 UNIX 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 prop-
- er interface to use.
-
- libl(--ll_l) The library for lex(1).
-
- libm(--ll_m) The math library, _l_i_b_m.
-
- libtermcap(--ll_t_e_r_m_c_a_p)
- The terminal independent operation library package. (See
- termcap(3).)
-
- liby(--ll_y) The library for yacc(1).
