intro - Introduction to library functions
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(3) library. They are contained in the stan-
dard 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 com-
piler flags needed to use these functions.
(3X) Various special libraries. The manual pages documenting their functions specify
the library names.
Look at the header of the manual page for the author(s) and copyright conditions. Note
that these can be different from page to page!
