How to specify zlib inflation size












-1














Is there a way to specify a certain number of inflated clear text in zlib? The sample code zpipe.c reads of size CHUNK (16384 bytes) but I do not see where to specify an inflated size. For example, if I only want to read the first 10 bytes before determining if I want to continue the inflation. Is that possible?



Updating question per request:



I am parsing out some zlib deflated content, which has a header. The header determines the type of content (binary or otherwise). In some cases, I just want to deflate the header. At other times, I need to deflate the entire thing. I was wondering if I could write a deflation function that will return X bytes of inflated text, irrespective of the count of deflated text.






c zlib

    I don't understand what you're asking. You should elaborate with an example of what you imagine doing.

If you set avail_out to n, then inflate() will return at most n bytes of uncompressed data.

            Run scheduled task as local user group (not BUILTIN)

            0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
