We already have the function that returns the filehandle.  We are
specifically talking about adding the function that returns the filename.

Sorry, this section of my message should have been deleted.  My first
thought was that this is how you would get the apr_file_unique() function,
but as I said above, that support shouldn't be added to the library

Huh?????  The API that we are discussing _has_ two functions for this.
One to get the filename and one to get the directory name.  What we are
talking about here is how you deal with a default compiled-in path versus
the one from the environment variable.  The solution that has been
proposed is a flag that is passed in.  But that flag is only going to have
an affect on Unix systems.  I would much rather just use logic like:

/* Add more if statemets for other platforms */
if (getenv("TEMP")) {
    return getenv("TEMP")
if (getenv("TEMPDIR")) {
    return getenv("TEMPDIR")
return PATH_TMP

This allows the system administrator to override the platform default.
What it removes is the ability to get the default value of PATH_TMP if the
administrator has overridden it.
