For a good reason though. It is nonstandard and of limited use.
Use sprintf() (or even better snprintf()) for this.

While we are at hot botton pressing ...

Get a documentation for ANSI-C and it comes with a nice list of
generally available and documented functions which are available
in any compliant implementation. This is in no way specific to UNIX.

For the UNIX specific stuff have a look at the SuS specification
(or the various standards that make up UNIX).

http://www.opengroup.org/onlinepubs/007908799/index.html

On a HP-UX box you can have a look in the man page and look at the
section "STANDARDS CONFORMANCE" which lists all the standards
this specific function follows. If it is missing then use of that
function is not portable and you likely don't want it ...
