### SHD_REPORTINT Field - ulFlag

ulFlag (ULONG) Specifies the reason for the interrupt. This field defines the following flags:

ERROR
STREAM_STOP_NOW
SHD_READ_COMPLETE
SHD_WRITE_COMPLETE

Note: Do not set SHD_READ_COMPLETE or SHD_WRITE_COMPLETE if not returning a buffer.

The STREAM_STOP_NOW flag is required. It forces the stream handler to release all buffers that have not been returned. Issue this flag if DDCMD_ STOP or if the VSD has remaining buffers.
