.bpcmds (Display Breakpoint Commands)
The .bpcmds command displays the commands that were used to set each of the current breakpoints.
user mode, kernel mode
live, crash dump
For more information about and examples of how to use breakpoints, other breakpoint commands and methods of controlling breakpoints, see Using Breakpoints.
If it is unclear whether a particular breakpoint is set at an address, at a symbolic reference, or at a symbol, use the .bpcmds command to shows which breakpoint command was used to create it. The command that was used to create a breakpoint determines its nature:
The bp (Set Breakpoint) command sets a breakpoint at an address.
The bu (Set Unresolved Breakpoint) command sets a breakpoint on a symbolic reference.
The bm (Set Symbol Breakpoint) command sets a breakpoint on symbols that match a specified pattern. If the /d switch is included, it creates zero or more breakpoints on addresses (like bp), otherwise it creates zero or more breakpoints on symbolic references (like bu).
The ba (Break on Access) command sets a data breakpoint at an address.
The output of .bpcmds reflects the current nature of each breakpoint. Each line of the .bpcmds display begins with the command used to create it (bp, bu, or ba) followed by the breakpoint ID, and then the location of the breakpoint.
If the breakpoint was created by ba, the access type and size are displayed as well.
If the breakpoint was created by bm without the /d switch, the display indicates the breakpoint type as bu, followed by the evaluated symbol enclosed in the @!"" token (which indicates it is a literal symbol and not a numeric expression or register). If the breakpoint was created by bm with the /d switch, the display indicates the breakpoint type as bp.
Here is an example:
0:000> bp notepad!winmain 0:000> .bpcmds bp0 0x00000001`00003340 ; 0:000> bu myprog!winmain breakpoint 0 redefined 0:000> .bpcmds bu0 notepad!winmain; 0:000> bu myprog!LoadFile 0:000> bp myprog!LoadFile+10 0:000> bm myprog!openf* 3: 00421200 @!"myprog!openFile" 4: 00427800 @!"myprog!openFilter" 0:000> bm /d myprog!closef* 5: 00421600 @!"myprog!closeFile" 0:000> ba r2 myprog!LoadFile+2E 0:000> .bpcmds bu0 notepad!winmain; bu1 notepad!LoadFile; bp2 0x0042cc10 ; bu3 @!"myprog!openFile"; bu4 @!"myprog!openFilter"; bp5 0x00421600 ; ba6 r2 0x0042cc2e ;
In this example, notice that the output of .bpcmds begins with the relevant command ("bu", "bp", or "ba"), followed by the breakpoint number (with no intervening space).
Notice that because breakpoint number 0 was originally set using bp, and then was redefined using bu, the display shows its type as "bu".
Notice also that breakpoints 3, 4, and 5, which were created by the bm commands shown in this example, are displayed as either type "bp" or type "bu", depending on whether the /d switch was included when bm was used.
