You can invoke Dump History from within an application or directly 

from the command line.

„

From within an application, one of:

Š

The C system function 

Š

BfvHistoryDumpModChan (args)
See Volume 1 of the Bfv API Reference Manual for detailed 

information on how to use the BfvHistoryDump... functions. 

„

As a stand-alone utility, as follows:

dh [-C] [-f] [-r [-b]] [-R file offset] [-P pktver] [-H hdr_dir] module channel

-C 

Clear the history buffer, do not print 

entries.

-f

Display history output continuously until 

the program is terminated by the user. 

This option works best only on lightly 

loaded systems. For best speed, use the 

options -r -b, then later interpret the 

output using -R. 

-r 

Do a raw dump of the uninterpreted 

history data in ASCII form.

-b

Do dump as binary, for use with -r.

-R file offset

Indicates that history interpretation is to 

be done using a previously obtained binary 

history file. (Such files are obtained from 

system crash dumps or by processing the 

output of dh -r -b). A filename and starting 

offset in hex must be specified. When -R is 

used, the module and channel numbers are 

not required on the command line.

-P

For use with -R. Forces the packet version 

to the specified value (0 or 1).

-H hdr_dir

Read from the directory hdr_dir to create 

name tables. Used if modifications were 

made to commands or additional command 

header files are available after compilation 

and distribution of the program.
