Stopping Execution When Modified

To stop program execution when the contents of an address is written to:

(dbx) stop modify &variable

Keep these points in mind when using stop modify:

• The event occurs when a variable gets written to even if it is the same value.

• The event occurs before the instruction that wrote to the variable is executed, although the new contents of the memory are preset by dbx by emulating the instruction.

• You cannot use addresses of stack variables, for example, auto function local variables.
