  There are no standard library functions to do this; you'll have to write
code to do it yourself; it isn't that difficult to write.  Either that, or you
can steal the code from one of the many packages that are available on the net
that have it; for example, I believe rn does ~ expansion.

  Strtok, if it exists on your system, will do this.  See the man page.  If it
doesn't exist on your system, there are (I believe) several freely
redistributable versions of it floating around the net, or (once again) you
can steal it from another program that has a freely redistributable version of
it.
