We want to add the capability to not only get the time but also set the time, but there's no "setter" for the "getter" time(). The first ones that come into mind are gettimeofday() and settimeofday(). However, they take a struct timezone argument that doesn't make sense - even the man pages says "The use of the timezone structure is obsolete; the tz argument should normally be specified as NULL." And POSIX says "Applications should use the clock_gettime() function instead of the obsolescent gettimeofday() function." The ...timeofday() functions work with microseconds while the clock_...time() functions work with nanoseconds. Given that we expect our targets to support only 1/10 of seconds the microseconds look preferable at first sight. However, already microseconds require the cc65 data type 'long' so it's not such a relevant difference to nanoseconds. Additionally clock_getres() seems useful. In order to avoid code duplication clock_gettime() takes over the role of the actual time getter from _systime(). So time() now calls clock_gettime() instead of _systime(). For some reason beyond my understanding _systime() was mentioned in time.h. _systime() worked exactly like e.g. _sysremove() and those _sys...() functions are all considered internal. The only reason I could see would be a performance gain of bypassing the time() wrapper. However, all known _systime() implementations internally called mktime(). And mktime() is implemented in C using an iterative algorithm so I really can't see what would be left to gain here. From that perspective I decided to just remove _systime().

<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 <url
|
|
url="library.html" name="cc65 Library Overview">.
|
|
|
|
<em/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

on stderr and aborts the program.

<tag/Description/The function returns a character from the current input device.
|
|
Device must first have been OPENed and then designated as the input channel by the CHKIN routine.
|
|
When this function is called, the next byte of data available from the device is returned.
|
|
Exception is the routine for the keyboard device (which is the default input device).

Unless a device has been OPENed and designated as the

current output channel using the CHKOUT routine, the character is

printed to the screen, which is the default output device. If the

cassette is the current device, outputting a byte will only add it to

192-byte buffer is full.

<tag/Description/Purpose of this function is to send a byte of data over

the serial bus. In order for the data to be received, the serial

secondary address if necessary. This routine always buffers the

|
sent with an End or Identify (EOI).

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

<item>On most platforms, the function needs to copy a small stub loader to

some memory area outside the program space. This may collide with other

|
programs. See the platform specific docs on this.
|
|
<item>Because it is necessary to terminate the running program before the

|
memory can be reused to load the new one, there is a high chance that the
|
|
function may not be able to return on errors.
|
|
<item>The command line is passed to the new program in the same way as cc65
|
|
programs expect the command line. If the new program is not a cc65 generated

program, it may not be able to read it.

<item>On several platforms, namely the CBMs and the Atari, the disk drives get

confused when opening/closing files between directory reads. So for example a

program that reads the list of files on a disk, and after each call to
|
|
<tt/readdir/, opens the file to process it, will fail.<newline>
|
|
Possible solutions are reading the directory into memory before processing the
|
|
file list, or to reset the directory by seeking to the correct position after
|
|
opening/closing a file:
|
|
<verb>
|
|
seekdir (DIR, telldir (DIR));
|
|
</verb>
|
|
Platforms known to work without problems are: Apple.
