* FUNCTION NAME : tst_tmpdir, tst_rmdir
*
* FUNCTION TITLE : Create/remove a testing temp dir
*
* SYNOPSIS:
* void tst_tmpdir();
* void tst_rmdir();
*
* AUTHOR : Dave Fenner
*
* INITIAL RELEASE : UNICOS 8.0
*
* DESCRIPTION
* tst_tmpdir() is used to create a unique, temporary testing
* directory, and make it the current working directory.
* tst_rmdir() is used to remove the directory created by
* tst_tmpdir().
*
* Setting the env variable "TDIRECTORY" will override the creation
* of a new temp dir. The directory specified by TDIRECTORY will
* be used as the temporary directory, and no removal will be done
* in tst_rmdir().
*
* RETURN VALUE
* Neither tst_tmpdir() or tst_rmdir() has a return value.
*
