BL - List Breakpoints

List all breakpoints defined by the BP and BR commands.

Syntax:

──── BL ──────────────────────────────────────────────────────

Parameters: none.

Results & Notes:

BL lists the definitions of all currently defined breakpoints. An example of this follows:

bl
0 e  0158:00005874 [DOSOPEN]  5 (5) ".P*;G"
1 d  0158:00007384 [DOSHOLDSIGNAL]
2 e  %fff461a4 [_tkSchedNext]  12 (15) ".P*"
3 dT %fff474e4 [_PGSwitchContext]
4 d  %1a022298 [DOS32WRITE]  10 (10)
5 e  W2 0030:0000ffcc [Ppid]
6 dI E1 0000:00000000   5 (5) "DW TASKNUMBER L1"
7 e  I1 00002e7
##

Breakpoint definitions are of two forms:

• The general layout of the BP breakpoint definition is:

  n st addr [symbol] pc (mc) "cmd, cmd, ...."
  
  

• The general layout of the BR breakpoint definition is:

  n st tn addr [symbol] pc (mc) "cmd, cmd, ...."
  
  

Each of the fields has the following meaning:

n

The breakpoint number assigned to the given breakpoint.

The status of the breakpoint:

d

Disabled breakpoint. See BD command
e
Enabled breakpoint. See BE command.

The suffix T signifies that the breakpoint is a time-stamp breakpoint created using the BT command.

The suffix I indicates that the address has become invalid.

tn
The register breakpoint type (t) and size (n):

R

Read breakpoint.
W
Write breakpoint.
I
I/O breakpoint.

Note: I/O breakpoints are only available to Pentium (and later) processors. The support for I/O breakpoints was introduced into the Kernel Debugger with fix pack 29 for Warp 3.0 and base Warp 4.0.

addr
The address at which the breakpoint is defined.
[symbol]
The breakpoint offset to the nearest symbolic address, if it exits. See LN and WA commands for information on listing and loading symbol definitions.
pc
The remaining passcount for this breakpoint. If a passcount is not defined then this value is not displayed. See BP and BR commands for more information on passcounts.
(mc)
The initial passcount defined for this breakpoint. If no passcount was defined then this value is not displayed. See BP and BR commands for more information on passcounts.
"cmd, cmd, ... "
A list of commands to be executed when the breakpoint fires. Each command is separated by commas and the entire string is enclosed in quotes. If no command string is defined then this field is not displayed. See BP, BR and Z commands for more information on breakpoint command lists.
