语法：

buffer_decompress(buffer);

Returns: Buffer ID

描述

With this function you can decompress a previously compressed buffer using zlib compression. You supply the buffer ID to decompress, and the function will return a new buffer ID that contains the uncompressed data. If the decompression has failed (for example, you are supplying a buffer that hasn't been compressed) then the function will instead return a value less than 0.

例如：

var cmpBuff = buffer_load("Player_Save.sav");
var srcBuff = buffer_decompress(cmpBuff);
global.DataString = buffer_read(srcBuff, buffer_string);

The above code will first load a saved buffer, then decompress it and finally read the string data from the decompressed buffer into a global variable.
