.Nm intro
|
|
.Nd introduction to the C libraries
|
|
.Sh DESCRIPTION
|
|
This section provides an overview of the C
|
|
library functions, their error returns and other
|
|
common definitions and concepts.
|
|
Most of these functions are available from the C library,
|
|
.Em libc
|
|
(see
|
|
.Xr libc 3 ) .
|
|
Other libraries, such as the math library,
|
|
.Em libm ,
|
|
must be indicated at compile time with the
|
|
.Fl l
|
|
option of the compiler.
|
|
.Pp
|
|
A subset of the
|
|
.Xr libc functions
|
|
are available from Fortran;
|
|
they are described separately in
|
|
.Xr intro 3f .
|
|
.Pp
|
|
The various libraries (followed by the loader flag):
|
|
.Bl -tag -width "libc (-lc)"
|
|
.It Xr libc Pq Fl l Ns Ar c
|
|
Standard C library functions. (See
|
|
.Xr libc 3 . ) When using the C compiler
|
|
.Xr cc 1 ,
|
|
it is not necessary
|
|
to supply the loader flag
|
|
.Fl l Ns Ar c
|
|
for these functions.
|
|
There are several `libraries' or groups of functions included inside of
|
|
.Xr libc : the standard
|
|
.Tn I/O
|
|
routines,
|
|
database routines,
|
|
bit operators,
|
|
string operators,
|
|
character tests and character operators,
|
|
des encryption routines,
|
|
storage allocation, time functions, signal handling and more.
|
|
.It Xo
|
|
.Xr libcurses
|
|
.Pf ( Fl l Ns Ar curses
|
|
.Fl l Ns Ar termcap )
|
|
.Xc
|
|
Terminal independent screen management routines
|
|
for two dimensional non-bitmap display terminals.
|
|
(See
|
|
.Xr curses 3 . )
|
|
.It Xr libcompat Pq Fl l Ns Ar compat
|
|
Functions which are obsolete but are available for compatibility with
|
|
.Bx 4.3 .
|
|
In particular,
|
|
a number of system call interfaces provided in previous releases of
|
|
.Bx
|
|
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.
|
|
.\" .It Xr libkvm
|
|
.It Xr libl Pq Fl l Ns Ar l
|
|
The library for
|
|
.Xr lex 1 .
|
|
.\" .It Xr libln
|
|
.It Xr libm Pq Fl l Ns Ar m
|
|
The math library,
|
|
.Em libm .
|
|
The math library is loaded as needed by the Pascal compiler
|
|
.Xr pc 1 ,
|
|
but not by the C compiler which requires the
|
|
.Fl l Ns Ar m
|
|
flag.
|
|
(See
|
|
.Xr math 3 . )
|
|
.It Xr libmp Pq Fl l Ns Ar mp
|
|
.\" .It Xr libom
|
|
.\" Old math library.
|
|
.It Xr libplot Pq Fl l Ns Ar plot
|
|
Device independent plotting functions.
|
|
(See
|
|
.Xr plot 3 . )
|
|
.It Xr libplotf77 Pq Fl l Ns Ar plotf77
|
|
The device independent plotting functions for fortran.
|
|
(See
|
|
.Xr plot 3 . )
|
|
.\" .It Xr libresolv Pq Fl l Ns Ar resolv
|
|
.\" Routines for network address resolution.
|
|
.It Xr libtermcap Fl l Ns Ar termcap
|
|
The terminal independent operation library package. (See
|
|
.Xr termcap 3 . )
|
|
.\" .It libvt0.a
