- introduction to the C libraries
This section provides an overview of the C
library functions, their error returns and other
common definitions and concepts.
Most of these functions are available from the C library,
Other libraries, such as the math library,
must be indicated at compile time with the
option of the compiler.
The various libraries (followed by the loader flag):
Standard C library functions.
When using the C compiler
it is not necessary
to supply the loader flag
for these functions.
There are several libraries or groups of functions included inside of
character tests and character operators,
des encryption routines,
storage allocation, time functions, signal handling and more.
| libcurses(-lcurses-l termcap)
Terminal independent screen management routines
for two dimensional non-bitmap display terminals.
Functions which are obsolete but are available for compatibility with
BSD 4.3 .
a number of system call interfaces provided in previous releases of
have been included for source code compatibility.
Use of these routines should, for the most part, be avoided.
The manual page entry for each compatibility routine
indicates the proper interface to use.
Functions used to access kernel memory are in this library.
They can be used
against both a running system and a crash dump.
