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.
