NAME
     intro - introduction to library functions

DESCRIPTION
     This section describes functions that may be found in
     various libraries. The library functions are those other
     than the functions which directly invoke UTek system
     primitives, described in section two.  This section has the
     libraries physically grouped together. This is a departure
     from older versions of the UNIX Programmer's Reference
     Manual, which did not group functions by library.  The
     functions described in this section are grouped into various
     libraries:

     (3c)
         The 3c functions are the standard C library functions.

     (3f)
         The 3f functions are all functions callable from
         FORTRAN. These functions perform the same jobs as do the
         3c functions.

     (3m)
         These functions constitute the math library, libm. They
         are automatically loaded as needed by the FORTRAN
         compiler f77(1). The link editor searches this library
         under the -lm option.  Declarations for these functions
         may be obtained from the include file <math.h>.

     (3n)
         These functions constitute the internet network library.

     (3s)
         These functions constitute the standard I/O package; see
         stdio(3s). These functions are in the C library.
         Declarations for these functions may be obtained from
         the include file <stdio.h>.

     (3t)
         These functions constitute the curses and termcap
         libraries, and contain routines for screen management.
         These functions are loaded by using the arguments
         -lcurses and -ltermlib (or -ltermcap) with cc(1).

     (3d)
         These functions constitute the database management
         library.

     (3mp)
         These functions constitute the multiple precision math
         library.

     The functions in the (3c), (3n), and (3s) routines ,
     constitute library libc, which is automatically loaded by
     the C compiler cc(1) and the FORTRAN compiler f77(1). The
     link editor ld(1) searches this library under the -lc
     option.  Declarations for some of these functions may be
     obtained from include files indicated on the appropriate
     pages.

DIAGNOSTICS
     Functions in the math library (3m) may return conventional
     values when the function is undefined for the given
     arguments or when the value is not representable.  In these
     cases, the external variable errno (see intro(2)) is set to
     the value EDOM (domain error) or ERANGE (range error).  The

     values of EDOM and ERANGE are defined in the include file
     <math.h>.
