DEBUGMSG
If you want to add Debugging output statements to your own code, you can use the following conventions:
Note the double (( ))s in these statements!
DEBUGMSGTL(("token", "statement of some kind: %s\n", "with printf arguments"));
This actually outputs two lines:
- A "trace" line showing where in the source it came from (that's what the T stands for)
- Your debugging line (when -Dtoken is turned on)
This should be the most common debugging statement used. It should be used for complete debugging lines.
For creating lines a piece at a time, start with DEBUGMSGTL followed by DEBUGMSG macros until you hit the newline ("\n"). This is a stupid example but shows how it works:
int total = 0;
DEBUGMSGTL(("token", "Calculating running total: "));
for(int i = 0; i < 5; i++) {
total = total + i;
DEBUGMSG(("token", " %d", total));
}
DEBUGMSG(("token", "\n"));
For printing OIDs you can use the DEBUGOID macro:
oid my_oid[] = { 1, 3, 6, 1}
size_t my_oid_len = 4;
DEBUGMSGTL(("token", "this is my oid: "));
DEBUGMSGOID(("token", my_oid, my_oid_len));
DEBUGMSG(("token", "\n"));
