Hello,
one of my customer developp applicatiom on Decmcc,
in an "acces module", they use :
Mcc_desframe_set_svr_and_reply
They have pb at first time with the memory allocation ( buffer=1024)
at the second time ( buffer=1024*2 = 2048)
at the third time (they have a message error (memory Allocation)
The question is:
Can we reserve directly for insteance 8k in this buffer (and how can we
do this?)
Or must we work with this limitation ?
PS: this pb occur only with iconic map
thanks for your Help ....

| 4155.1 | you can specify the Out-P buffer size | MOLAR::ROBERTS | Keith Roberts - Network Management Applications | Fri Nov 27 1992 12:24 | 22 |
I imagine that you are refering to the 'Out-P' Call Argument.
The Iconic Map is using a STATIC descriptor for Out-P .. the size if
1024 bytes. Because this isn't large enough for your data to return,
the Design Framework (DFW) is 'guessing' that twice that size might
work. In your case, this loop is repeating a few times until the
buffer *is* large enough.
There is no external way of changing the DFW Out-P buffer logic,
however you can detect when the buffer-too-small condition occurs, and
change Out-P yourself.
After calling Set-CVR-and-Reply, if the return status is ..
MCC_S_INSUFBUF
Then set p_callargs->p_out_p->mcc_w_curlen to 8192 (or what ever value
is best for your situation). This will tell the Iconic Map to create
a larger Out-P buffer (of your specified size) and call your Management
Module again.
