C++，获取当前工作路径

需要包含的头文件：

#include 
#include 

函数如下：

std::string GetCWD()
{
	const int MAX_LENGTH = 512;
    char buffer[MAX_LENGTH];

    getcwd(buffer, 512);
    std::string cwd = buffer;

    int pos = cwd.find("\");
    while (pos != cwd.npos)
    {
        cwd.replace(pos, 1, "/");
        pos = cwd.find("\");
    }

	return cwd;
}
