Variable column widths, string lengths in printf-style functions
By Vadim - Posted on April 5th, 2007
I have been programming in C for quite some time, but until recently I was not aware that you could specify column widths and string limits using variables. I have neither seen this functionality used in any projects until I started working with OpenSER.
Specify a variable column width:
printf("%*d", width, number);
Specify a variable number of characters from a string:
printf("%.*s", width, string);
Can you please post a link to document explaining this feature

It's described under "The field width"
