Re: Sleep

[Daniel Aquino <mr.danielaquino@...>]

Well I already provided the source and I have it also at this url for now: http://fly.thruhere.net/projects/net_proxy/lua/lib/sleep/

I included everything bellow but I don't have a Mac so I can't help you there.


==sleep.c==
// unix bindings for sleep(seconds), usleep(microseconds), msleep(milliseconds).

#include <lua.h>
#include <lualib.h>
#include <lauxlib.h>
#include <unistd.h>

static int l_usleep(lua_State *L)
{
	usleep( luaL_checkint(L,-1) );
	return 0;
}

static int l_msleep(lua_State *L)
{
	usleep( luaL_checkint(L,-1) * 1000 );
	return 0;
}

static int l_sleep(lua_State *L)
{
	sleep( luaL_checkint(L,-1) );
	return 0;
}

int luaopen_sleep(lua_State *L)
{
	lua_register( L, "usleep", l_usleep );
	lua_register( L, "msleep", l_msleep );
	lua_register( L, "sleep",  l_sleep  );
  	return 1;
}

I guess plain Mac + gentoo was what I was looking for :-) !

The example I gave is very easy to support on winapi.

I could throw one together including makefile and visual studios
project if someone wants.

Should be easy to support sdl as well.

if there was a non-ANSI sleep surrounded by #ifdef's ?  after all,
there's the GNU-only readline....

Yes, admirable consistency, but it would be _convenient_ to have
os.sleep() around ;)

It isn't so easy to find one out there, without bringing in the whole
of LuaSocket, which feels inelegant.

PS. another solution is to use Alien to bring in Sleep (on Windows) or
usleep (on POSIX)
