This should help.

I do the C structures defined. But the functions return pointers to the
structures created by Tidy. So I have to Read the data into my local copy
using the pointer returned. Which I feel is very inefficient. I have just
started to play around with defining offset values for each location in the

Thanks, I worked out my issue was I was passing a null pointer to the
memory function and then calling my external function. The error I kept
getting was a type mismatch and did not make sense to me as the docs led me
to believe that the Memory steam was a declaration, not a function on an
actual p
Sorry,
hStream = Memory pPointer For Read

I don't have any simple runnable example right now, so I hope this helps:
Dim pPointer As Pointer
Dim hStream As Stream
Dim iYourData As Integer
Dim ii As Integer
Dim iNumberOfDataPoints As Integer = x
Dim itmp As Integer
pPointer = Alloc(SizeOf(gb.Integer), iNumberOfDataPoints)

Hi All,
Can someone give me a sample of using memory streams to read and write data
to/from memory.
I am needing to read data from a C structure allocated by the external
library (tidy) with the pointer returned to Gambas.
I read the page on external libraries many times before learning the Gamb
