14 This chapter describes all library functions excluding the
15 library functions described in chapter 2, which implement
16 system calls. There are various function groups which can be
17 identified by a letter which is appended to the chapter
18 number:
19
20
21 (3C)
22
23
24 These functions, the functions from chapter 2 and from
25 chapter 3S are contained in the C standard library libc,
26 which will be used by cc(1) by default.
27
28
29 (3S)
30
31
32 These functions are parts of the __stdio__(3S) library.
33 They are contained in the standard C library
34 libc.
35
36
37 (3M)
38
39
40 These functions are contained in the arithmetic library
2 perry 41 libm. They are used by the f77(1) FORTRAN compiler by
1 perry 42 default, but not by the cc(1) C compiler, which needs
43 the option ''-lm''.
44
45
46 (3F)
47

50 There are no special compiler flags needed to use these
51 functions.
