STREAMS/UX supports many of the System V STREAMS debugging tools.
Refer to Appendix D in the SVR4PG manual for a description of the System
V tools.
STREAMS/UX Tracing and Logging |
 |
STREAMS/UX supports tracing and logging. See Appendix D and
the strace(1M), strclean(1M), strerr(1M), and log(7) man pages in the SVR4PG manual for more information
about these tools. Some differences exist in the user interfaces
of these tools on HP-UX. These differences are described in Chapter
3 of this manual and the corresponding HP-UX man pages.
cmn_err() and printf() |
|
HP-UX supports the DKI function cmn_err(). See Appendix D of the SVR4PG manual and the Unix
System V Release 4 Device Driver Interface/Driver-Kernel Interface
(DDI/DKI) Reference Manual for more information about cmn_err().
Also, HP-UX supports printf for STREAMS/UX modules and drivers. If a STREAMS/UX
module or driver calls printf, HP-UX prints the requested message on the system
console, and stores the message in the dmesg buffer.
Dump Module Example |
|
The SVR4PG manual presents a STREAMS dump module in Appendix D.
The dump module traces messages flowing into and out of another STREAMS
module. Appendix D contains the module source code. Programmers
can copy and tailor the code to develop their own debugging tool
for HP-UX. The sample master file entry and dump module include
statements must be changed for HP-UX. See Chapter 2 and Chapter
5 of this manual for more information about the HP-UX master file
and STREAMS/UX include statements.
strdb and adb |
|
STREAMS/UX provides strdb for debugging. strdb can be used with the HP-UX crash and adb tools for debugging.
