检查文件中是否存在带有通配符的文件 [英] check if file exists with wildcards in filename

问题描述

我需要为c ++：

  if（fileExists（c：\foo\bar * .txt ））{
 cout<< 文件已存在; 
} else {
 cout<< file does not exist; 
} 
  

它与这里描述的几乎相同：如何检查文件是否在Java中有通配符？，但是对于c ++

解决方案

由于您没有指定平台，因此有几个选项。对于POSIX兼容系统，有此解决方案的答案（信用他不是我的）：

您可以使用[ glob（）] [1 ] POSIX库函数。

或者对于窗口有

链接到 setargv。 obj （或 wsetargv.obj ）和argv []将会为你类似于Unix shell的做法：

我无法保证

或者对于一个简单的跨平台库，您可以尝试 shwild 或 wildcmp ，或使用此问题的答案自行编写。 / p>

What i Need for c++:

if( fileExists("c:\foo\bar*.txt") ){
  cout << "file exists";
}else{
  cout << "file does not exists";
}

Its nearly the same as descripted here: How to check a file if exists with wildcard in Java? , but for c++

解决方案

Since you haven't specified a platform there are a few options. For POSIX compliant systems there is the answer from this solution (credit his not mine):

You can use the [glob()][1] POSIX library function.

alternatively for windows there is this solution:

Link with setargv.obj (or wsetargv.obj) and argv[] will be globbed for you similar to how the Unix shells do it:

I can't vouch for how well it does it though.

Or for a simple cross platform library you could try shwild or wildcmp or write your own with the answer to this question.
