Ahh, so it's not attempting to turn it into an "acsii" string, just storing
raw binary data... Ok that makes sense now, thanks for the help.

If I understand the code right, your trying to pass in to
appendBinaryStringInfo an "address" or reference to the n8, n16, or n32

the appendBinaryStringInfo function), I never seem to see any data, The
variable pointer that references the "n8, n16, or n32" value is not holding
any data in the appendBinaryStringInfo function.
How are you looking at the data? If you're treating the pointer as if it
were a null-terminated string, it's likely that the first byte is a null
character much of the time. Since this is binary data (not character
data), you'll need to look at the individual bytes. If you're using gdb,
use 'x' command instead of the 'p' command. If you've thrown a printf()
into the code, you can't use a "%s" format specifier, you'll have to look
at the bytes one at a time using something like "%02X".
