<sect>Introduction<p>
|
|
|
|
cc65 is a C compiler for 6502 based systems. It implements a subset of the ISO
|
|
C standard plus additional functions specially crafted for 6502 systems or
|
|
just some of the supported machines. This function refrence describes the
|
|
available functions together with any limitations.
|
|
|
|
For an overview about the available libraries, their purpose, and any
|
|
differences to the ISO standard, please have a look at the <htmlurl
|
|
url="library.html" name="cc65 Library Overview">.
|
|
|
|
<bf/Note:/ Standard C functions are listed here, but not described in detail.
|
|
Since these functions behave identical on all standard compliant systems, they
|
|
are described in any book covering standard C.
|
|
|
|
Each entry for a function contains a detailed description

<tag/Description/<tt/set_brk/ allows a user program to handle breaks within the

<itemize>
|
|
<item>The function is only available as fastcall function, so it may only

|
|
<item>The stub saves the zero page registers used by the C runtime and switches
|
|
to a small break handler stack. This means that it is safe to execute C code,
|
|
even if C code was interrupted. Be careful however not to use too many local
|
|
variables, and do not enable stack checks for the handler function or any other
|
|
function called from it.
|
|
<item>The <tt/brk_pc/ variable points to the <tt/BRK/ instruction. If you want
|
|
the continue with the interrupted code, you have to adjust <tt/brk_pc/,
|
|
otherwise the <tt/BRK/ instruction will get executed over and over again.

<item>The use of this function is discouraged. Please use <tt/<ref id="remove"

name="remove">/ instead, which is a native ANSI C function and does the same.
|
|
<item>This function is not available on all cc65 targets (depends on the
|
|
availability of file I/O).
|
|
<item>The function is only available as fastcall function, so it may only

|
be used in presence of a prototype.
|
|
<item>Instead of <tt/unlink/, <tt/<ref id="remove" name="remove">/ should be
|
|
used, which has the same semantics, but is more portable, because it conforms
|

to the ISO C standard.
