HP-UX Changes to STREAMS/UX Data Structures

STREAMS/UX data structures are almost identical to those described in the SVR4.2 Driver manual. STREAMS/UX places additional restrictions on how some of these structures can be accessed.

STREAMS/UX data structures that differ from the descriptions in the SVR4.2 Driver manual are described below. Data structures identical to those described in the SVR4.2 manual are not listed below.

STREAMS/UX data structures contain some declarations for fields used by STREAMS/UX internally that are not visible to the STREAMS/UX programmer. The programmer will not be affected by these fields except that the sizeof function will return a larger value.
