I'm looking to list and store the contents of a directory in a struct using C on Windows.
I'm not necessar开发者_运维百科ily looking for anyone to write out the code I'm looking for, rather point me in the right direction when it comes to which library I should be looking at.
I've been Googling for a few hours now and all I'm finding is C#, C++ solutions so any help would be greatly appreciated.
Just like everyone else said (with FindFirstFile, FindNextFile and FindClose)... but with recursion!
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
bool ListDirectoryContents(const char *sDir)
{
WIN32_FIND_DATA fdFile;
HANDLE hFind = NULL;
char sPath[2048];
//Specify a file mask. *.* = We want everything!
sprintf(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)
{
//Build up our file path using the passed in
// [sDir] and the file/foldername we just found:
sprintf(sPath, "%s\\%s", sDir, fdFile.cFileName);
//Is the entity a File or Folder?
if(fdFile.dwFileAttributes &FILE_ATTRIBUTE_DIRECTORY)
{
printf("Directory: %s\n", sPath);
ListDirectoryContents(sPath); //Recursion, I love it!
}
else{
printf("File: %s\n", sPath);
}
}
}
while(FindNextFile(hFind, &fdFile)); //Find the next file.
FindClose(hFind); //Always, Always, clean things up!
return true;
}
ListDirectoryContents("C:\\Windows\\");
And now its UNICODE counterpart:
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
bool ListDirectoryContents(const wchar_t *sDir)
{
WIN32_FIND_DATA fdFile;
HANDLE hFind = NULL;
wchar_t sPath[2048];
//Specify a file mask. *.* = We want everything!
wsprintf(sPath, L"%s\\*.*", sDir);
if((hFind = FindFirstFile(sPath, &fdFile)) == INVALID_HANDLE_VALUE)
{
wprintf(L"Path not found: [%s]\n", sDir);
return false;
}
do
{
//Find first file will always return "."
// and ".." as the first two directories.
if(wcscmp(fdFile.cFileName, L".") != 0
&& wcscmp(fdFile.cFileName, L"..") != 0)
{
//Build up our file path using the passed in
// [sDir] and the file/foldername we just found:
wsprintf(sPath, L"%s\\%s", sDir, fdFile.cFileName);
//Is the entity a File or Folder?
if(fdFile.dwFileAttributes &FILE_ATTRIBUTE_DIRECTORY)
{
wprintf(L"Directory: %s\n", sPath);
ListDirectoryContents(sPath); //Recursion, I love it!
}
else{
wprintf(L"File: %s\n", sPath);
}
}
}
while(FindNextFile(hFind, &fdFile)); //Find the next file.
FindClose(hFind); //Always, Always, clean things up!
return true;
}
ListDirectoryContents(L"C:\\Windows\\");
Probably You are looking for these functions: FindFirstFile, FindNextFile, and FindClose.
To list file contents you can search a directory with these APIs: FindFirstFileEx, FindNextFile and FindClose. You'll need to #include <windows.h>
, that'll get you access to the Windows API. They're C functions and so compatible with C++. If you want "specifically C++", try searching for listing directories using MFC.
