TBHawkNL - Include and samples

[Michael Hartlef]

Hi folks,

on my trip of conversion I took my IBP HawkNL conversion and tried to bring it into thinBasic. That one sample I have works. The hard part was getting strings in and out, so other function declarations could be wrong. If you improve the header, then please post your new file.

Btw. HawkNL is a Network library that supports UDP and you can find it here:

Have fun
Michael

Edit: Updated the download with the sample fix of Eros.

Before someone asks, this was more an eductional task for me. I think the native TCPUDP module will do the jobs great. I just wanted to see if I can get this thing here to work.

Mike,

first thanks!
Second I get a GPF, sorry. I get it here:


'(* list all the local addresses *)
console_writeline( "local addresses are:")
alladdr = nlGetAllLocalAddr(varptr(count))
'console_writeline("count:" & str$(count))

WHILE count > 0
retstr = nlAddrToString(alladdr, strptr(str2))
console_write( " " & PEEK$(ASCIIZ,retstr,255) & " -> ")
retstr = nlGetNameFromAddr(alladdr, strptr(str3))
console_writeline( PEEK$(ASCIIZ,retstr,255))
'console_writeline("alladdr->" & str$(alladdr))
alladdr = alladdr + LEN(addr)
'console_writeline("alladdr->" & str$(alladdr))
count = count - 1
wend


Count is equal to 3 (I have 2 lan plus one wireless) but I get printed only the first lan. Than GPF.
WHILE/WEND loop is executed but when restart, the second time it GPF in nlAddrToString function

Ciao

Mike thanks for the message in the quote. I would have been confused and wondering.

Mike,

I think I've found. Change from



dim retstr as ASCIIZ


to



dim retstr as dword



Because nlAddrToString in reality return a pointer to an ASCIIZ buffer and not an ASCIIZ. So it is a DWORD. An ASCIIZ string without a defined size in thinBasic is something more close to a dynamic string than a memory buffer.

Thanks EROS! I said, I had big time troubles with strings

Petr ???

;D

Ok, Ok, I go back to bed. Sorry man!

In any case, thanks a lot for pointing me to this lib I didn't know. Seems very interesting having a low level net lib.

thinBasic TCP/UDP module is quite high level and hide the complexity of such task bringing to thinBasic user the easy part. But sometime someone wants more. So this lib seems very good. I have to read licence and see if I can add to thinBasic arsenal.

Thanks
Eros

Sure, it would be nice to see some kind of things of it in the TCPUDP module. Did you saw the HawkVoice module?
