The printa() function

void printa(aggregation)
void printa(string format, aggregation)

The printa() action enables you to display and format aggregations. See Chapter 9, Aggregations, in Solaris Dynamic Tracing Guide for more detail on aggregations. If a format value is not provided, the printa() action only traces a directive to the DTrace consumer. The consumer that receives that directive processes and displays the aggregation with the default format. See Chapter 12, Output Formatting, in Solaris Dynamic Tracing Guide for a more detailed description of the printa() format string.
