我们从Python开源项目中，提取了以下6个代码示例，用于说明如何使用os.tmpnam()。
def test_tmpnam(self): with warnings.catch_warnings(): warnings.filterwarnings("ignore", "tmpnam", RuntimeWarning, r"test_os$") warnings.filterwarnings("ignore", "tmpnam", DeprecationWarning) name = os.tmpnam() if sys.platform in ("win32",): # The Windows tmpnam() seems useless. From the MS docs: # # The character string that tmpnam creates consists of # the path prefix, defined by the entry P_tmpdir in the # file STDIO.H, followed by a sequence consisting of the # digit characters '0' through '9'; the numerical value # of this string is in the range 1 - 65,535. Changing the # definitions of L_tmpnam or P_tmpdir in STDIO.H does not # change the operation of tmpnam. # # The really bizarre part is that, at least under MSVC6, # P_tmpdir is "\\". That is, the path returned refers to # the root of the current drive. That's a terrible place to # put temp files, and, depending on privileges, the user # may not even be able to open a file in the root directory. self.assertFalse(os.path.exists(name), "file already exists for temporary file") else: self.check_tempfile(name) # Test attributes on return values from os.*stat* family.
