For the example shown, you could search for lines starting with arbitrary whitespace followed by printf( as the start line and continue to the next line ending with ); followed by arbitrary whitespace.
If you're in vi at the start of the line containing printf you could use the % command to find the ending ) (assuming that the format string and any string constants being printed don't contain any mismatched parentheses).

If you're not already inside an editor making changes to your source code, you could use ed, ex, sed, or awk, to make similar changes (assuming you want to comment out ALL printf statements or only want to comment out printf statements with a specific format string).

But, if this is awk code (where the trailing semicolon is optional and in come cases the parentheses are also optional), different rules would be needed.

I have a lot of c code like this. I just put in a ridiculous amount of printf statements for debugging and I want to comment all of them out except the ones that contain "ACCEPT" and "REJECT"

Code:

            cmp_str9 = strcmp("return", strings_line_tokens[lower_bound_of_big_boy_counter ]);
            printf("4006 lower_bound_of_big_boy_counter %d \n", lower_bound_of_big_boy_counter);
            printf("4007 strings_line_tokens[lower_bound_of_big_boy_counter] %s \n", 
            strings_line_tokens[lower_bound_of_big_boy_counter]);
            //int
            if(cmp_str9 == 0)
            {
                printf("3402 checking return stuff \n");
                return_match_flag = 1;
                lower_bound_of_big_boy_counter++;
                get_function_type_for_proper_return(symbol_table_functions, type,id, 
                                         scope_char, symbol_table_functions_counter, function_type_for_proper_return);
                printf("3407 lower_bound_of_big_boy_counter %d \n", lower_bound_of_big_boy_counter);
                printf("3408 strings_line_tokens[lower_bound_of_big_boy_counter] %s \n", 
                strings_line_tokens[lower_bound_of_big_boy_counter]);
                printf("3410 function_type_for_proper_return %s \n", function_type_for_proper_return);
