SYNOPSIS
#include <sys/debug_message.h>

void debug_message(string text)
void debug_message(string text, int flags)

DESCRIPTION
Prints the given text to stdout, stderr, the <host>.debug.log file,
or any combination of these.

The parameter <flags> is a combination of bitflags determining the
target and the mode of writing.

The target flags are: DMSG_STDOUT, DMSG_STDERR and DMSG_LOGFILE.
If the flag DMSG_STAMP is given, the message is prepended with the
current date and time in the format 'YYYY.MM.DD HH:MM:SS '.

If <flags> is given as 0, left out, or contains no target
definition, debug_message() will print to stdout and to the logfile.

EXAMPLE
debug_message("This goes to stdout and the logfile.\n");
debug_message("This goes to stderr.\n", DMSG_STDERR);
debug_message("This goes to stdout and stderr.\n"
, DMSG_STDOUT | DMSG_STDERR);

debug_message("This goes to stdout and the logfile, with timestamp.\n"
, DMSG_STAMP);
debug_message("This goes to stdout and has the timestamp in front.\n"
, DMSG_STDOUT | DMSG_STAMP);

HISTORY
