• During the dbx session, if you want to load a module dynamically, first
set the $module_path dbx variable and then use the addobj command
to load the module, as in the following example:
(dbx) set $module_path /project4/mod_dir
(dbx) addobj kmodC
To verify that modules are being loaded from the correct location, turn on
verbose module-loading using any one of the following methods:
• Specify the -module_verbose dbx command option.
• Set the DBX_MODULE_VERBOSE environment variable to any integer
value.
• Set the $module_verbose dbx variable to a nonzero value.
2.1.4 Examining Memory Contents
To examine memory contents with dbx, use the following syntax:
address/count[mode]
The count argument specifies the number of items that the debugger
displays at the specified address, and the mode argument determines how
dbx displays memory. If you omit the mode argument, the debugger uses
the previous mode. The initial default mode is X (hexadecimal). Table 2–1
lists the dbx address modes.
