And the code can be wrapped in macro to simplify the works :)

#define GET_BUFFER(size) ….
#define FREE_BUFFER(…)

How about to do so:

void foo(int size) {
int asize = size;
if (asize > 1024)
asize = 1;
int buffer[asize];
int *array = buffer;
if (asize != size)
array = malloc(size * sizeof *array);

if(!array) {
//Error out here
return;
}

for(int i=0; i array[i] = i;
}
…

if (array != buffer)
free(array);
}

Comment on Westinghouse TVs are great… by Clark Cox

None of the solutions proposed by Westinghouse have helped, I’ve come to the conclusion that my PS3 will never be able to get a reliable HDMI signal into my TV, and stand by my assertion that I will never again buy a Westinghouse TV.

I finally broke down and got an HDFury2. It is essentially an HDMI-to-VGA or an HDMI-to-component converter. I run the HDMI from my PS3 into it, and then connect to the VGA port on my TV.

Thank god for the analog hole.

All normal compilers do stack allocations correctly, not by simply decrementing the stack pointer. For example (gcc (GCC) 3.4.2 (mingw-special)):
.00401730: 51 push ecx
.00401731: 89E1 mov ecx,esp
.00401733: 83C108 add ecx,008 ;”◘”
.00401736: 3D00100000 cmp eax,000001000 ;” ► ”
.0040173B: 7210 jb .00040174D —–↓ (1)
.0040173D: 81E900100000 sub ecx,000001000 ;” ► ”
.00401743: 830900 or d,[ecx],000 ;” ”
.00401746: 2D00100000 sub eax,000001000 ;” ► ”
.0040174B: EBE9 jmps .000401736 —–↑ (2)
.0040174D: 29C1 sub ecx,eax
.0040174F: 830900 or d,[ecx],000 ;” ”
.00401752: 89E0 mov eax,esp
.00401754: 89CC mov esp,ecx
.00401756: 8B08 mov ecx,[eax]
.00401758: 8B4004 mov eax,[eax][04]

first off. former tech, wow. i can’t even read ur post. its like one big run-on sentence with words missing all over that would help it to even make sence what you are saying.

second, i am having a similar issue with my westinghouse tv. its a 26″ LCD TV i use as a pc monitor, ps2 screen, & regular tv screen. its a model SK-26H730S, Part # TW-55807-C026C.

it worked fine until i installed a blu-ray drive into my pc. then the blue would start to play & a few seconds into even the start of the menu loading it would freeze the screen.

at first i thought it was the blu-ray software, so i un-installed/re-installed the software three different times (each time going through my entire system to make sure all traces were deleted). bought new cables for my pc to my tv (even though i had the right DVI to HDMI, & DVI to VGA cables). finally i took my pc over to my friends, hooked it up to his 19″ LCD HD pc monitor & it worked just fine. i brought it back hooked it up again & still having the same problem.

a few forums i have been to said that a firmware update would fix it. but i went to the westinghouse website & got the same message as clark cox. i registered it & still have the same message.

does anyone know anything that could help?

Hmmm the issue here is at the begining of May Westinghouses Service Provider stopped taking calls and responding to emails for a few reason the lack of comunication that you all have gotten from the service center is in direct result of Westinghouses Offices not responding to request to get issues resolved and also due to none payment of services for 90+ days.

And in response to “David”. Are you a Westinghouse rep?

Anyway, as with Clark Cox: Model number TX-47F439S, Part number TW -512 -51212-CO47A

Would love to have some support after nine months….

Geeez, what a run-around you have received, Clark. I really feel sorry for you – having been “there” with many manufacturers over many years. Today, I try not to get so involved with details, and try not to become so emotionally involved. Sometimes we just get scr**ed on a product and recourse is extremely difficult and involved – if available at all.

I too. have the same Westinghouse TV, and while it has pretty much worked adequately, the sound system firmware is not very functional. In fact I just called again today, and the “firmware is still in progress”, heh-heh, right! So we will call about once a month, hoping that that it might eventually be ready.
