.SH NAME
|
|
intro \- Introduction to library functions
|
|
.SH 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:
|
|
.IP (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
|
|
.BR cc (1)
|
|
by default.
|
|
.IP (3S)
|
|
These functions are parts of the
|
|
.BR stdio (3)
|
|
library. They are contained in the standard C library libc.
|
|
.IP (3M)
|
|
These functions are contained in the arithmetic library libm. They are
|
|
used by the
|
|
.BR f77 (1)
|
|
FORTRAN compiler by default, but not by the
|
|
.BR cc (1)
|
|
C compiler, which needs the option \fI\-lm\fP.
|
|
.IP (3F)
|
|
These functions are part of the FORTRAN library libF77. There are no
|
|
special compiler flags needed to use these functions.
|
|
.IP (3X)
|
|
Various special libraries. The manual pages documenting their functions
|
|
specify the library names.
|
