I am seeing a strange problem when I try to set IORegistry properties in my audio driver.

If I have the following code:

UInt32 n;

n=0; setProperty("zero", n, sizeof(UInt32)*8);
n=2; setProperty("two", n, sizeof(UInt32)*8);
n=4; setProperty("four", n, sizeof(UInt32)*8);
n=8; setProperty("eight", n, sizeof(UInt32)*8);
n=16;setProperty("sixteen", n, sizeof(UInt32)*8);
n=32;setProperty("thirty_two", n, sizeof(UInt32)*8);

Am I doing something wrong here?

I'm not sure, but IORegistryEntry.h declares a different argument type for the value (unsigned long long), so try:

UInt64 n;

Maybe the compiler isn't promoting it right, and you're luckily getting a loop index passed for one of the two registers for the 64- bit value? -- Shaun Wexler MacFOH http://www.macfoh.com
