Using Simulator printf("%s")

Barry Shonbeck

Can anyone tell me how to print the value of a source code string in the simulator? I am trying to use the simulator printf() function in a breakpoint assignment as follows:

bs \assertions\assert\81, 1, "printf(\"%s.\",\\assertions\\assert\\debugstr)"
debugStr is defined within Assert()as follows:
char debugStr[CHARS_PER_LINE];
I have tried many variations on this theme but all report:
<printf: argument 2 invalid>

Thanks,
Barry

    Type the following in the comand window:

    d debugStr, &(((debugStr)) [sizeof(debugStr)-1])

    This should display the string. If it does, then change your breakpoint to:

    bs \assertions\assert\81, 1, "d debugStr, &(((debugStr)) [sizeof(debugStr)-1])"

    I'm pretty sure this will work. You may need to use the EXEC debugger function, but I don't think so.

    The reason that the printf Debugger Function doesn't work is because its arguments must be Debugger Variables and not variables in your program.
