       intro - Introduction to library functions

       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

       (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

       (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  com-
              piler, 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 docu-
              menting their functions specify the library  names.

       Look  at  the  header of the manual page for the author(s)
       and copyright conditions.  Note that these can be  differ-
       ent from page to page!
