+ See below some functions declarations for Visual Basic.
+
+ Frequently Asked Question:
+
+ Q: Each time I use the compress function I get the -5 error (not enough
+ room in the output buffer).
+
+ A: Make sure that the length of the compressed buffer is passed by
+ reference ("as any"), not by value ("as long"). Also check that
+ before the call of compress this length is equal to the total size of
+ the compressed buffer and not zero.

+
+ Got the answer! (I haven't had time to check this but it's what I got, and
+ looks correct):
+
+ He has the following routines working:
+ compress
+ uncompress
+ gzopen
+ gzwrite
+ gzread
+ gzclose
+
+ Declares follow: (Quoted from Carlos Rios <c_rios at sonda.cl>, in Vb4 form)
+
+ #If Win16 Then 'Use Win16 calls.
+ Declare Function compress Lib "ZLIB.DLL" (ByVal compr As
+ String, comprLen As Any, ByVal buf As String, ByVal buflen
+ As Long) As Integer
+ Declare Function uncompress Lib "ZLIB.DLL" (ByVal uncompr
+ As String, uncomprLen As Any, ByVal compr As String, ByVal
+ lcompr As Long) As Integer

+ String, ByVal mode As String) As Long

+
+ Here is another example from Michael <michael_borgsys at hotmail.com> that he
+ says conforms to the VB guidelines, and that solves the problem of not
+ knowing the uncompressed size by storing it at the end of the file:
+
+ 'Calling the functions:
+ 'bracket meaning: <parameter> [optional] {Range of possible values}
+ 'Call subCompressFile(<path with filename to compress> [, <path with
+ filename to write to>, [level of compression {1..9}]])
+ 'Call subUncompressFile(<path with filename to compress>)
+
+ Option Explicit

+ Private Const SUCCESS As Long = 0
+ Private Const strFilExt As String = ".cpr"
+ Private Declare Function lngfncCpr Lib "zlib.dll" Alias "compress2" (ByRef
+ dest As Any, ByRef destLen As Any, ByRef src As Any, ByVal srcLen As Long,
+ ByVal level As Integer) As Long
