我对C语言比较陌生，遇到了一个问题。我想列出给定的目录，搜索所有的文件或子目录，写下文件的名称和最后一次访问的时间。但是每次在sprintf_s（）之后，它都会给我Access violation。我想这和我的指针在递归函数中作为参数有关。所以这是我的代码：

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<errno.h>
#include<windows.h>
#include<direct.h>
#include<stdbool.h>
#define __STDC_WANT_LIB_EXT1__ 1

bool ListFromDirectory(const char* sDir) {//recursive functions for listing through the directory
    WIN32_FIND_DATA fdFile;
    HANDLE hFind = NULL;

    char sPath[2048];

    //Specify a file mask. *.*
     sprintf_s(sPath, "%s\\*.*", sDir);
    if ((hFind = FindFirstFile(sPath, &fdFile)) == INVALID_HANDLE_VALUE)
    {
        printf("Path not found: [%s]\n", sDir);
        return false;
    }

    do
    {
        //Find first file will always return "."
        //    and ".." as the first two directories.
        if (strcmp(fdFile.cFileName, ".") != 0
            && strcmp(fdFile.cFileName, "..") != 0)
        {
            LPSYSTEMTIME lpSystemTime;

            //Is the entity a File or Folder?
            if (fdFile.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
            {
                printf("Directory: %s\n", sPath);
                ListFromDirectory(sPath);
            }
            else {
                printf("File: %ls\n", fdFile.cFileName);
                FILETIME localFiletime;
                if (FileTimeToLocalFileTime(&fdFile.ftLastWriteTime, &localFiletime)) {
                    SYSTEMTIME sysTime;
                    if (FileTimeToSystemTime(&localFiletime, &sysTime)) {
                        printf("%ls is last modified at %.2d-%.2d-%4d %.2d:%.2d:%.2d\n",
                            fdFile.cFileName,                            
                            sysTime.wMonth, sysTime.wDay, sysTime.wYear,
                            sysTime.wHour, sysTime.wMinute, sysTime.wSecond);
                    }
                }
            }
        }
    } while (FindNextFile(hFind, &fdFile)); //Find the next file.

    FindClose(hFind);

    return true;
}
int main() {
    char c[12] = "E:\\Windows\\";
    ListFromDirectory(c);
    return 0;
}

sprintf_s（）之后的错误：在0x7A85EF8C（ucrtbased.dll）处引发异常：0xC0000005：访问冲突写入位置0x00760000。
