Question of function return value

[picobsd]

Hi, I am reading ModuleTurorialv1.pdf, and testing it's code on my psp develop platform.

I am a unix C programmer, and I have never developed on portable device such as PDA or PSP, Now I am confused with a function's C code in this PDF document.

-------------------- code fragement start here ------------
const char*
sv_check_permissions (int client)
{
const char* p;
sceKernelDelayThread (10000);
if (client == 123)
p = "yes";
else
p = "no";
return p;
}
-------------------- code fragement end here ------------

the above is a simple pure export module in that doc, As a C programmer, I know that the pointer p is a AUTO variable, It will be destroied when the function returned, I mean the p will point a Invaild area after the function returned, because p is nether a static pointer nor a heap poniter (use malloc), I worried this may cause the application crash?
why do this is safe in PSP, could someone tell me the reason, thank you!

do I make myself clear?

You are not returning the address of P, you're returning what P points to. In this case, you are returning the address of a static string (in the text segment).

Oh, thank you! It's const. I make a big mistake.
