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(3) library.  They are contained in the stan-
              dard 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 com-
              piler flags needed to use these functions.

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