How to find out a character position ?

[balakrishnan]

$str="1\n234\n1234567890";

$pos=10;

in the above, i need to find out a newline character position which is previous to 10th character of $str.
Any ideas?

my $pos_of_nl = rindex $str, "\n", 10-1;

(whether it's 10-1, 10-2 etc. depends on how exactly you're counting... feel free to finetune)
