RE: user space (2)

Sorry - didn't answer all of your question.

The 'User Space Header' is only created by certain API's - usually the
'List' APIs (QUSLOBJ - list object into user space for example). Those
API's do indeed create a header of a certain format. In that case, to
add some of your own data to the user space you probably should follow
the entry sizes as defined by whatever API that populated the space.

But if you just want to use it as a work space, you can create one, get
the pointer, and add data in any format you want by tying datanames to
the user space pointer as I mentioned.

Again, hope it helps

Subject: user space


Does anybody has a sample program that write data to user space?  I've
written several apps to retrieve data from it but has never try to write
data to it. 
 
Did a bit research and it seems like QUSCHGUS is the only api that allow
me to change the data in user space.  If that is the case, how does the
user space header get formatted?  How can QUSCHGUS api guarantee each
entry in the user space are the same length (There is a field in the use
space header that tells you the entry size ==> I'm, therefore, assuming
that each entry in the user space must have the same size.)?
