...or initialize a variable with it:

static char template[] = "/tmp/fooXXXXX";
...
	mktemp(template);

It depends on the application which variant is more appropriate.

Btw., this has *not* been the expected behaviour in the pre-ANSI era,
so if you're porting a very old program, you could sometimes stumple
across this problem.  That's why "gcc -traditional" doesn't make
constant strings read/only, but you're strongly encouraged to do the
right thing instead of relying on this hack.
