dtrace discuss - May 2007 - Check

could you tell me what is the type of the return here just to check something,
thx:
#!/usr/sbin/dtrace -s
#pragma D option quiet

/*
 * Declare Globals
 */
dtrace:::BEGIN
{
	ICMP_IE = 0;
	LINES = 20; line = 0;
}

/*
 * Print Header
 */
profile:::tick-1sec { line--; }

profile:::tick-1sec
/line <= 0 /
{
	

	line = LINES;
}

/*
 * Save Data
 */
mib:::icmpInEchos		{ ICMP_IE += arg0;   }
/*
 * Print Output
 */
profile:::tick-1sec
{
	printf("%d",
	    ICMP_IE);
	/* clear values */
	ICMP_IE   = 0;
	
}

I''m sorry. I don''t understand your question. what
"return" are you
talking about, and which "here" are you referring to?

is there any special reason why you''re not using an aggregation here:
  @icmp_ie = sum(arg0); ?

you''d do a printa() and clear() (or was it trunc()? I always confuse 
those two) instead -> see the DTrace guide
