Runtime-Support
Functions
Some
of
the tasks that a C program must perform (such
as
floating-point
arithmetic, string operations, and dynamic memory allocation)
are
not part
of
the C language. The runtime-support functions,
which
are
included
with
the
C compiler,
are
standard functions that perform these tasks. The runtime-
support library
rts
.lib
contains the object code for each
of
the functions
described in this section; the library
rts.
src
contains the source
to
these
functions
as
well
as
to
other functions and routines. If you
use
any
of
the
runtime-support functions,
be
sure
to
include
rts.
lib
as
linker input when
you link your C program.
This section
is
divided into three parts:
• Part 1 describes header files and discusses their functions.
• Part 2 summarizes the runtime-support functions according
to
category.
• Part 3
is
an
alphabetical reference.
You
can
find these topics on the
following
