c - C语言创建文件夹的方法

Question

如何为电子邮件管理器创建一个新文件夹，我有这段代码，但它不起作用。

 void create_folder() {
   int check;
   char * dirname;
   clrscr();
   printf("Enter a directory path and name to create a folder (C:/name):");
   gets(dirname);
   check = mkdir(dirname);

   if (!check)
     printf("Folder created\n");

   else {
     printf("Unable to create folder\n");
     exit(1);
   }
   getch();
   system("dir/p");
   getch();
 }

使用这个:

 void create_folder() {
   int check;
   char dirname[128];
   clrscr();
   printf("Enter a directory path and name to create a folder (C:/name):");
   fgets(dirname, sizeof(dirname), stdin);
   check = mkdir(dirname);

   if (!check)
     printf("Folder created\n");

   else {
     printf("Unable to create folder\n");
     exit(1);
   }
   getch();
   system("dir/p");
   getch();
 }

您的目录名字符串未分配，请改用字符数组。
