C++ (Cpp) GetBufferFromZipArchive Examples

Example #1

File: StartupCache.cpp Project: mxOBS/deb-pkg_icedove

// NOTE: this will not find a new entry until it has been written to disk!
// Consumer should take ownership of the resulting buffer.
nsresult

      memcpy(*outbuf, entry->data, entry->size);
      *length = entry->size;
      return NS_OK;
    }
  }
