What does function + xxxx mean

WINDBG
1

Hi,

I have a driver and it is crashing and in windbg I see statement as below

customs!testfuction()+1235

wht does this statement mean, what does this number after the + symbol
represent.

Any information is helpful.

Thanks,
Kedar.

A byte offset from the function; if you don’t have symbols, this is
“address + byte offset” whereas if you do have symbols it is “address +
instructions” (which are not necessarily the same thing, because code
need not be organized linearly).

Generally, when the offset is a large number (0x1d475) it is symptomatic
of using export symbols. In that case the “address to symbol” converter
has found the nearest symbol and added the appropriate offset. Not
terribly useful in my experience.

The instruction at offset 0x1235 from the beginning of function testfuction() in customs module caused the exception.
