The `-break-watch' Command

--------------------------

Synopsis

........

      -break-watch [ -a | -r ]

   Create a watchpoint.  With the `-a' option it will create an

'access' watchpoint, i.e., a watchpoint that triggers either on a read

from or on a write to the memory location.  With the `-r' option, the

watchpoint created is a 'read' watchpoint, i.e., it will trigger only

when the memory location is accessed for reading.  Without either of

the options, the watchpoint created is a regular watchpoint, i.e., it

will trigger when the memory location is accessed for writing.  *Note

Setting Watchpoints: Set Watchpoints.

   Note that `-break-list' will report a single list of watchpoints and

breakpoints inserted.

{No value for `GDBN'} Command

.............................

The corresponding {No value for `GDBN'} commands are `watch', `awatch',

and `rwatch'.

Example

.......

Setting a watchpoint on a variable in the `main' function:

     (gdb)

     -break-watch x

     ^done,wpt={number='2',exp='x'}

     (gdb)

     -exec-continue

     ^running

     (gdb)

     *stopped,reason='watchpoint-trigger',wpt={number='2',exp='x'},

     value={old='-268439212',new='55'},

     frame={func='main',args=[],file='recursive2.c',

     fullname='/home/foo/bar/recursive2.c',line='5'}

     (gdb)

   Setting a watchpoint on a variable local to a function.  {No value

for `GDBN'} will stop the program execution twice: first for the

variable changing value, then for the watchpoint going out of scope.

     (gdb)

     -break-watch C

     ^done,wpt={number='5',exp='C'}

     (gdb)

     -exec-continue

     ^running

     (gdb)

     *stopped,reason='watchpoint-trigger',

     wpt={number='5',exp='C'},value={old='-276895068',new='3'},

     frame={func='callee4',args=[],

     file='../../../devo/gdb/testsuite/gdb.mi/basics.c',

     fullname='/home/foo/bar/devo/gdb/testsuite/gdb.mi/basics.c',line='13'}

     (gdb)

     -exec-continue

     ^running

     (gdb)

     *stopped,reason='watchpoint-scope',wpnum='5',

     frame={func='callee3',args=[{name='strarg',

     value='0x11940 \'A string argument.\''}],

     file='../../../devo/gdb/testsuite/gdb.mi/basics.c',

     fullname='/home/foo/bar/devo/gdb/testsuite/gdb.mi/basics.c',line='18'}

     (gdb)

   Listing breakpoints and watchpoints, at different points in the

program execution.  Note that once the watchpoint goes out of scope, it

is deleted.

     (gdb)

     -break-watch C

     ^done,wpt={number='2',exp='C'}

     (gdb)
