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.
