mab command
-r
specifies read access
-w
specifies write access
-rw
specifies read/write access (this is the default value)
llce
is a low-level conditional expression that can be specified in any order with flags.
Examples
To display the memory access breakpoint:
To set a MAB by address:
To set a MAB on 4 bytes at a given address:
To set a MAB on variable j when it changes:
To set a “change” MAB:
(eInspect 1,480):mab
MAB
addr = 0x080000e0
segid = 65535
mabtype = 2
global = 0
haltloop = 0
length = 1
There is no global MAB set
(eInspect 3,880): mab *0x8000370
(eInspect 3,880): c
Continuing.
Process (3, 880) received DS_EVENT_MAB (seg:65535, addr:0x08000370,
pc:0xa4bd4c1

(eInspect 1,480):
