Для Linux (я исправил ошибки в коде выше):
void remove_dir(char *path)
{
struct dirent *entry = NULL;
DIR *dir = NULL;
dir = opendir(path);
while(entry = readdir(dir))
{
DIR *sub_dir = NULL;
FILE *file = NULL;
char* abs_path new char[256];
if ((*(entry->d_name) != '.') || ((strlen(entry->d_name) > 1) && (entry->d_name[1] != '.')))
{
sprintf(abs_path, "%s/%s", path, entry->d_name);
if(sub_dir = opendir(abs_path))
{
closedir(sub_dir);
remove_dir(abs_path);
}
else
{
if(file = fopen(abs_path, "r"))
{
fclose(file);
remove(abs_path);
}
}
}
delete[] abs_path;
}
remove(path);
}
Для окон:
void remove_dir(const wchar_t* folder)
{
std::wstring search_path = std::wstring(folder) + _T("/*.*");
std::wstring s_p = std::wstring(folder) + _T("/");
WIN32_FIND_DATA fd;
HANDLE hFind = ::FindFirstFile(search_path.c_str(), &fd);
if (hFind != INVALID_HANDLE_VALUE) {
do {
if (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
if (wcscmp(fd.cFileName, _T(".")) != 0 && wcscmp(fd.cFileName, _T("..")) != 0)
{
remove_dir((wchar_t*)(s_p + fd.cFileName).c_str());
}
}
else {
DeleteFile((s_p + fd.cFileName).c_str());
}
} while (::FindNextFile(hFind, &fd));
::FindClose(hFind);
_wrmdir(folder);
}
}
