+tst_tmpdir \- create a unique testing directory and make it current.
+tst_rmdir \- remove the directory created by \fBtst_tmpdir\fR.
+\fBvoid tst_tmpdir()
+void tst_rmdir()
+extern char *TESTDIR;\fR
+The \fBtst_tmpdir()\fR function uses the first three characters of the
+\fBTCID\fR global variable as the prefix in forming a unique directory name
+(via \fBtempnam\fR(3S)).  The directory is then created and made the current
+working directory.
+If \fBtst_tmpdir()\fR cannot form a unique directory name, create the
+directory, or \fBchdir\fR to the directory, it uses \fBtst_brk()\fR to issue
+"BROK" messages for all test cases.  It then exits via \fBtst_exit()\fR.
+Because \fBtst_tmpdir()\fR exits in the event of a problem, a test must call
+it \fBbefore\fR performing any operations that would require running a
+cleanup routine.
+The \fBtst_rmdir()\fR function recursively removes the directory created by
+\fBtst_tmpdir()\fR.  This function should be used \fBonly\fR as a companion
+to \fBtst_tmpdir()\fR and should be called immediately prior to the test
+exiting via \fBtst_exit()\fR.
+\fBtst_rmdir()\fR uses the \fBsystem\fR(3S) library routine (which in turn
+calls \fBfork\fR(2)), so tests that use it \fBcannot\fR treat SIGCLD as an
+unexpected signal.
+Users may gain access to the name of the temporary directory by declaring the
+external character pointer \fBTESTDIR\fR.
+The \fBtst_rmdir()\fR function will check the \fBTESTDIR\fR global variable
+to ensure that the user is not attempting to remove the root directory or
+some unspecified directories with a "*" parameter.  All error/warning
+messages are delivered through \fBtst_res()\fR.
