how can I return a value within embedded assembler?

Hi,

does anybody know how I can write an embedded ASM function that returns the actual PSR value? I prefered to go on like this:

int getCpsr( void )
{
int currentCPSR;
MRS currentCPSR, CPSR
return currentCPSR;
}

how can I return a value within embedded assembler?

Thanks,

but this is also ARM machine language instruction. I cannot use this inline assembler
__asm".....
