You must build a char string that will contain the data (the fields in a structure are always in a contigous memory space, so this is why you can use a char string.)

Unfortunately, you cannot use this structure directly from VFP (because it contains a pointer (sa_data is a pointer to char, in fact)). The string you must build must have 6 bytes:

- the first 2 bytes: the sa_family in binary format
- the next 4 bytes: a pointer to a string that will contain sa_data

You must use an third-party product (as my Pointers Class that you can download from the Files section) that adds pointer features to VFP, in order to send data to this function.

If you use my Pointers Class:

lnsa_family = ... && Your value
lcsa_data = ... && Your value, max 14 chars
*-- Instantiate a Pointers control object
SET CLASSLIB TO POINTERS ADDITIVE
loPointers=CREATEOBJECT('Pointers')
RELEASE CLASSLIB POINTERS
*-- Convert the sa_family field to binary format on 2 bytes
lcsa_family = loPointers.NumberToWordString(lnsa_family)
*-- Get a pointer to sa_data string
lcpsa_data = loPointers.GetPointer(lcsa_data, "STRUCTURE")
*-- Build the "structure"
lcSockAddr = lcsa_family + lcpsa_data

lcSockAddr is the value that you must pass by reference to the bind function as the 2nd param.

Hope I was clear, :)
