Dereference of out-of-bounds pointer

i used cvi 5.5 and
when i try to go over an array that is alloc with malloc i got
"Dereference of out-of-bounds pointer : 1 bytes (1 elements) past end of array"
how i can avoid this error ?
i must do it because i use API of microsoft (GetIpNetTable)

Can you not call GetIpNetTable with a size of Zero initially, which should tell you how much space to allocate of size MIB_IPNETTABLE structure.
Then allocate MIB_IPNETTABLE structure + 1 or even MIB_IPNETTABLE structure * 2.

You are allocating size of MIB_IPNETTABLE structure and still getting the error ?

Regards

there is no problem with the allocation
i have problem when i get to the table entry
the cvi has a range checking and because of that
it doesnt let me to run the line table[1]
its thinks that its have only one entry in the table

You can disable the user protection with the
SetBreakOnProtectionErrors function in the utility library.

See the section on user protection in chapter 1 of the
_LabWindows/CVI Programmer Reference Manual_.
