NAME
       intro - Introduction to library functions

DESCRIPTION
       This chapter describes all library functions excluding the library
       functions described in chapter 2, which implement system calls.  There
       are various function groups which can be identified by a letter which
       is appended to the chapter number:

       (3C)   These functions, the functions from chapter 2 and from chapter
              3S are contained in the C standard library libc, which will be
              used by cc(1) by default.

       (3S)   These functions are parts of the stdio(3S) library.  They are
              contained in the standard C library libc.

       (3M)   These functions are contained in the arithmetic library libm.
              They are used by the f77(1) FORTRAN compiler by default, but not
              by the cc(1) C compiler, which needs the option -lm.

       (3F)   These functions are part of the FORTRAN library libF77.  There
              are no special compiler flags needed to use these functions.

       (3X)   Various special libraries.  The manual pages documenting their
              functions specify the library names.
