DESCRIPTION
The DL macro is used to print logging or debugging messages using a debugger. The nana(1) command generates a set of debugger commands which are then sourced into gdb(1) to implement the logging. If you don't run the executable under gdb(1) then no tracing will occur. The arguments are:
format,... - a printf(3) style argument list containing the message
guard - print only if the guard is true.
handler - the code that does the printing. Default: fprintf
param - a parameter to be passed off to the handler. Default: stdout
See nana.info for details on configuring the behaviour.
