Unzip Downloaded Zip File from Server

cocos2d-x
1

I have added code from assest Manager class for Unzip Zip File

I am using unzGetGlobalInfo
if (unzGetGlobalInfo(zipfile, &global_info) != UNZ_OK)
in this method error is

Error expression preceding parentheses of apparent call must have (pointer-to-) function type

I got this Error with each method . unzClose , unzOpenCurrentFile , unzCloseCurrentFile

Here Some Piece of Code .

	unzFile *zipfile = unzOpen(pathName.c_str());


if (!zipfile)
{
	CCLOG("can not open downloaded zip file %s", pathName.c_str());
	return;
}


unz_global_info global_info;
if (unzGetGlobalInfo(zipfile, &global_info) != UNZ_OK)
{
	CCLOG("can not read file global info of %s", pathName.c_str());
	unzClose(zipfile);
	return;
}

unzGetCurrentFileInfo(zipfile, &global_info);

//Loop to extract all files
long i;
for (i = 0; i < global_info.number_entry; ++i)
{
	unz_file_info file_info;
	char filename[100];
	if (unzGetCurrentFileInfo(
		zipfile,
		&file_info,
		filename,
		100,
		NULL, 0, NULL, 0) != UNZ_OK)
	{
		CCLog("could not read file infon");
		unzClose(zipfile);
		return;
	}

	// Buffer to hold data read from the zip file.
	char read_buffer[8192];

	string str(filename);

	if (str.find(".png") != string::npos || str.find(".gif") != string::npos){

		CCLog("debug extracting file %s", filename);
		// Check if this entry is a directory or file.
		const size_t filename_length = strlen(filename);
		if (filename[filename_length - 1] == '/')
		{
			// Entry is a directory, so create it.
			printf("dir:%sn", filename);

		}
		else
		{
			//Entry is a file, so extract it.
			CCLog("file:%sn", filename);
			if (unzOpenCurrentFile(zipfile) != UNZ_OK)
			{
				CCLog("could not open filen");
				unzClose(zipfile);
				return;
			}

			// Open a file to write out the data.
			string filepath = CCFileUtils::sharedFileUtils()->getWritablePath() + packageID + "_" + filename;
			CCLog("%s", filepath.c_str());
			FILE *out = fopen(filepath.c_str(), "wb");
			if (out == NULL)
			{
				CCLog("could not open destination filen");
				unzCloseCurrentFile(zipfile);
				unzClose(zipfile);
				return;
			}
			else
			{

				int error = UNZ_OK;
				do
				{
					error = unzReadCurrentFile(zipfile, read_buffer, READ_SIZE);
					if (error < 0)
					{
						printf("error %dn", error);
						unzCloseCurrentFile(zipfile);
						unzClose(zipfile);
						return;
					}

					// Write data to file.
					if (error > 0)
					{
						int dbuf = fwrite(read_buffer, error, 1, out); // You should check return of fwrite...
						CCLog("debug bytes written %d %s", dbuf, filename);
					}
				} while (error > 0);

				fclose(out);
			}
		}

		unzCloseCurrentFile(zipfile);


		// Go the the next entry listed in the zip file.
		if ((i + 1) < global_info.number_entry)
		{
			if (unzGoToNextFile(zipfile) != UNZ_OK)
			{
				printf("cound not read next filen");
				unzClose(zipfile);
				return;
			}
		}

	}

	unzClose(zipfile);

Plz help

Have you solved this?
tried this some time ago and have the same issue, for now i just make decompress as public, so i unzip it with AssetsManagerEx::decompress(filename); :sweat_smile:
