printf - output a formatted list to a filehandle
printf FILEHANDLE FORMAT, LIST
printf FORMAT, LIST
Equivalent to print FILEHANDLE sprintf(FORMAT, LIST), except that $\
(the output record separator) is not appended. The first argument
of the list will be interpreted as the printf format. If use locale is
in effect, the character used for the decimal point in formatted real numbers
is affected by the
LC_NUMERIC locale. See the perllocale manpage.
Don't fall into the trap of using a printf when a simple
print would do. The print is more efficient and less
error prone.
