Advanced Debugging

• finish. Finish current function, then break. Useful when you step into a function that you didn't mean to.

• return. Prematurely finish current function, then break. return 3 causes the function to prematurely finish with 3 as its return value.

• whatis treeptr. Prints data type of treeptr.

• whatis size_t. Prints out definition of type size_t.

• call factorial(5). Calls the function factorial with argument 5 and prints the result.

• x = 7. Sets program variable x to 7.

• display x. Print value of x every time the program stops.

• undisplay x. Turns off display mode for variable x.

• watch x. Breaks program whenever x changes.

• rwatch x. Breaks program whenever x's value is used. [x = 7; would cause a watch to stop, y = x; would cause a rwatch to stop, and x++ would cause both to stop.]

• clear 54. Clears breakpoint (if any) at line 54.

• file prog7. Change file to be debugged to prog7.

• info breakpoints. List current breakpoints.
