void tst_rmdir()
extern char *TESTDIR;
If tst_tmpdir() cannot form a unique directory name, create the directory, or chdir to the directory, it uses tst_brk() to issue "BROK" messages for all test cases. It then exits via tst_exit(). Because tst_tmpdir() exits in the event of a problem, a test must call it before performing any operations that would require running a cleanup routine.
The tst_rmdir() function recursively removes the directory created by tst_tmpdir(). This function should be used only as a companion to tst_tmpdir() and should be called immediately prior to the test exiting via tst_exit().
tst_rmdir() uses the system(3S) library routine (which in turn calls fork(2)), so tests that use it cannot treat SIGCLD as an unexpected signal.
Users may gain access to the name of the temporary directory by declaring the external character pointer TESTDIR.
