如何使用C语言进行文件的重命名及删除操作？

Posted 2023-05-11

参考技术A 在<stdio.h>包里有两个函数可以满足你的要求:
注意,这两个函数操作的文件必须要关闭,否则会执行失败,如果失败,执行完成后可以通过比较errno的值来确定失败原因.
重命名:
int rename(const char *oldname, const char *newname);
参数解释:
oldname:原文件名
newname:新文件名(可以指定全局路径来移动文件)
返回值:
0:成功
-1:失败,并将全局变量errno置为错误码

删除:
int remove(const char *filename);
参数解释:
filename:要删除的文件名
返回值:
0:成功
-1:失败,并将全局变量errno置为错误码本回答被提问者采纳

ArcPy 重命名拷贝删除图层

使用Python脚本进行图层的重命名拷贝及删除，并在过程中利用logging进行日志记录。

附上Python代码：

 1 # -*- coding: utf-8 -*-
 2 # nightroad
 3 import sys
 4 import arcpy
 5 import logging
 6 
 7 logging.basicConfig(level=logging.DEBUG,
 8                 format=‘%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s‘,
 9                 datefmt=‘%a, %d %b %Y %H:%M:%S‘,
10                 filename=‘log.txt‘,
11                 filemode=‘a‘)         
12 path = r"C:Users
ightroadAppDataRoamingESRIDesktop10.0ArcCatalog	est.sdeTEST"
13 arcpy.env.workspace = path
14 try:
15         print "delete line_1"
16         logging.info("delete line_1")
17         arcpy.Delete_management("line_1")
18         print "delete point_1"
19         logging.info("delete point_1")
20         arcpy.Delete_management("point_1")
21 except Exception as e:
22         print("no data or delete error!",e)
23         logging.warning("no data or delete error!")
24 try:
25         print "rename line"
26         logging.info("rename line")
27         arcpy.Rename_management("line", "line_1")
28         print "rename point"
29         logging.info("rename point")
30         arcpy.Rename_management("point", "point_1")
31         try:
32                 print "copy point"
33                 logging.info("copy point")
34                 arcpy.Copy_management(r"E:TEST.gdbTESTpoint","point")
35                 print "copy line"
36                 logging.info("copy line")
37                 arcpy.Copy_management(r"E:TEST.gdbTESTline","line")
38                 try:

41                         arcpy.Delete_management("line_1")
42                         print "delete point_1"
43                         logging.info("delete point_1")
44                         arcpy.Delete_management("point_1")
45                 except Exception as e:

47                         logging.error("delete error!")
48         except Exception as e:
49                 print("copy error!",e)
50                 logging.error("copy error!")
51 except Exception as e:
52         print("rename error!",e)
53         logging.error("rename error!")
