This is a bit friendlier than -// allocating memory with new[]: it won't lead to fragmentation, and the -// memory won't be touched unless needed. -// Note: because pipes don't allow random access, the structure of a zipfile -// created into a pipe is slightly different from that created into a file -// or memory. In particular, the compressed-size of the item cannot be -// stored in the zipfile until after the item itself. (Also, for an item added -// itself via a pipe, the uncompressed-size might not either be known until -// after.) This is not normally a problem. But if you try to unzip via a pipe -// as well, then the unzipper will not know these things about the item until -// after it has been unzipped. Therefore: for unzippers which don't just write -// each item to disk or to a pipe, but instead pre-allocate memory space into -// which to unzip them, then either you have to create the zip not to a pipe, -// or you have to add items not from a pipe, or at least when adding items -// from a pipe you have to specify the length. - - -/////////////////////////////////////////////////////////////////////////////// -// -// ZipAdd() -// -// Purpose: Add a file to a zip archive -// -// Parameters: hz - handle to an open zip archive -// dstzn - name used inside the zip archive to identify the file -// src - for a file (ZIP_FILENAME) this specifies the filename -// to be added to the archive; for other uses, see below -// len - for memory (ZIP_MEMORY) this specifies the buffer -// length; for other uses, this should be 0 -// flags - indicates usage, see below; for files, this will be -// ZIP_FILENAME -// -// Returns: ZRESULT - ZR_OK if success, otherwise some other value -// -ZRESULT ZipAdd(HZIP hz, const TCHAR *dstzn, void *src, unsigned int len, DWORD flags); -// ZipAdd - call this for each file to be added to the zip. -// dstzn is the name that the file will be stored as in the zip file. -// The file to be added to the zip can come -// from a pipe: ZipAdd(hz,"file.dat", hpipe_read,0,ZIP_HANDLE); -// from a file: ZipAdd(hz,"file.dat", hfile,0,ZIP_HANDLE); -// from a fname: ZipAdd(hz,"file.dat", "c:\\docs\\origfile.dat",0,ZIP_FILENAME); -// from memory: ZipAdd(hz,"subdir\\file.dat", buf,len,ZIP_MEMORY); -// (folder): ZipAdd(hz,"subdir", 0,0,ZIP_FOLDER); -// Note: if adding an item from a pipe, and if also creating the zip file itself -// to a pipe, then you might wish to pass a non-zero length to the ZipAdd -// function.
