查找文件夹下所有文件方法c++

代码如下：

void EnumFiles(const char *directory, int *count, char **result, int flag)//flag:2 bmp  1 bin
{
	WIN32_FIND_DATA FindFileData;
	HANDLE hFind;
	char pattern[MAX_PATH];
	int i = 0;
	char dir[MAX_PATH];
	// 开始查找
	strcpy(pattern, directory);
	strcat(pattern, "\\*.*");
	hFind = FindFirstFile(pattern, &FindFileData);

	if (hFind == INVALID_HANDLE_VALUE)
	{
		*count = 0;
	}
	else
	{
		do
		{
			if (flag == 0 && i >= MAX_IMG_NUM)
				continue;
			if ((flag == 1 || flag == 2) && i >= MAX_IMG_NUM)
				continue;
			if (strcmp(FindFileData.cFileName, ".") == 0 || strcmp(FindFileData.cFileName, "..") == 0)
				continue;
			memset(dir, 0, MAX_PATH);
			strcpy(dir, directory);
			strcat(dir, "\\");
			strcat(dir, FindFileData.cFileName);
			if (flag == 1)
			{
				int l = strlen(dir);
				if (dir[l - 1] == 'n' && dir[l - 2] == 'i' && dir[l - 3] == 'b')
				{
					strcpy(result[i++], dir);
				}
				else
					continue;
			}
			else if (flag == 2)
			{
				int l = strlen(dir);
				if (dir[l - 1] == 'p' && dir[l - 2] == 'm' && dir[l - 3] == 'b')
				{
					strcpy(result[i++], dir);
				}
				else
					continue;
			}
			else
				strcpy(result[i++], dir);
		} while (FindNextFile(hFind, &FindFileData) != 0);
	}
	// 查找结束
	FindClose(hFind);
	// 复制到结果中
	*count = i;
}
