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 com
piler, 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 docu
menting their functions specify the library names.
