CreateDirectory递归创建多级目录

目的：实现用CreateDirectory创建多级目录

1.引入静态库

#include "shlwapi.h"

#pragma comment(lib,"shlwapi.lib")

2.函数

const wchar_t* wcstrrchr(const wchar_t* str, const wchar_t wc)
{
    const wchar_t* pwc = NULL;
    for (int i=wcslen(str)-1;i>=0;i--)
    {
        if (str[i] == wc)
        {
            pwc = str + i;
            break;
        }
    }
    return pwc;
}  

bool createMultiDir(const wchar_t* path)
{
    if (path == NULL) return false;
    const wchar_t* pwcStrrchr = wcstrrchr(path,L‘\\‘);
    if (!pwcStrrchr) return false;
    if (PathIsDirectory(path)) return true;  

    wchar_t wsSubPath[MAX_PATH] = {};
    memset(wsSubPath,0,sizeof(wsSubPath));
    for (int i=0; i<pwcStrrchr-path; i++)
        wsSubPath[i] = *(path+i);
    createMultiDir(wsSubPath);
    if(CreateDirectory(path,NULL)) return true;
    return false;
}  

3.调用案例

createMultiDir(L"d:\\whish\\test\\好孩子\\宝马\\测试.txt"); //绝对路径
createMultiDir(L".\\whish\\test\\好孩子\\宝马\\测试.txt");//相对路径
