Stopping Execution When Variables Change

["andy wang" <ypwangreg@gmail.com>]

Hi, All:

Last question before Xmas :-) I want to find the same function in gdb
as in sun's dbx

I can't find it in GDB manual so I came here. Thanks in advanced!

============ the following is from sun dbx manual =========
topping Execution When Variables Change

To stop program execution if the value of a specified variable has
changed, type:

(dbx) stop change variable

Keep these points in mind when using the stop change command:

    * dbx stops the program at the line after the line that caused a
change in the value of the specified variable.

    * If variable is local to a function, the variable is considered
to have changed when the function is first entered and storage for
variable is allocated. The same is true with respect to parameters.

    * The command does not work with multithreaded applications.

For more information on specifying a change event, see change variable
and stop Command.
