  26 .SH NAME
  27 intro \- Introduction to library functions
  28 .SH DESCRIPTION
  29 This chapter describes all library functions excluding the library
  30 functions described in chapter 2, which implement system calls.  There
  31 are various function groups which can be identified by a letter which
  32 is appended to the chapter number:
  33 .IP (3C)
  34 These functions, the functions from chapter 2 and from chapter 3S are
  35 contained in the C standard library libc, which will be used by
  36 .BR cc (1)
  37 by default.
  38 .IP (3S)
  39 These functions are parts of the
  40 .BR stdio (3)
  41 library.  They are contained in the standard C library libc.
  42 .IP (3M)
  43 These functions are contained in the arithmetic library libm.  They are
  44 used by the
  45 .BR f77 (1)
  46 FORTRAN compiler by default, but not by the
  47 .BR cc (1)
  48 C compiler, which needs the option \fI\-lm\fP.
  49 .IP (3F)
  50 These functions are part of the FORTRAN library libF77.  There are no
  51 special compiler flags needed to use these functions.
  52 .IP (3X)
  53 Various special libraries.  The manual pages documenting their functions
  54 specify the library names.
  55 .SH AUTHORS
  56 Look at the header of the manual page for the author(s) and copyright
  57 conditions.  Note that these can be different from page to page!
