       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.
