To break on an access to a variable
You can also set breakpoints on a read, a write, or any access of a variable.
This helps to locate defects due to multiple functions accessing the same
variable. Suppose you want to break on the access of the variable num_checks.
("&num_checks" should still be in the entry buffer.)
1 Set the breakpoint by selecting Breakpoints
→
Set
→
Read/Write () .
2 R un the program by clicking on the Run action key.
When the program stops, the code window shows that the program stopped at
the next reference to the variable num_checks.
Try running the program a few more times to see where it stops. (Notice that
num_checks is passed by reference to interrupt_sim. Since counter points to the
same address as num_checks, the debugger stops at references to counter.)
3 Delete the access breakpoint. Select Window
→
Breakpoints, place the mouse
in the Breakpoint window, press and hold the right mouse button, and choose
Delete All Breakpoints.
