### ERRINFO Field - offaoffszMsg

offaoffszMsg (ULONG) Offset to the array of message offsets.

This is an offset to an array of 16-bit offsets to null-terminated strings. Each string is a printable message that offers varying levels of information. The first level is the least amount of detail, and the remaining levels offer more and more detail.

The first level of detail is always an error message string, in the following format:

        xxxnnnns

        where    xxx    is the product identifier

                 nnnn   is the message number

                 s      is the message severity letter

                          W = warning

                          E = error

                          S = severe error

                          U = unrecoverable
