Hi,
try with this:
FFITutorial>>getHostNameInto: hostName ofLenght: length
^self ffiCall: #( int gethostname(char *hostName, int length) ) library: 'Ws2_32.dll'. "... on Windows"
From Playground, you can then do:
| name len |
len := 50.
name:= ByteArray new: len.
FFITutorial new getHostNameInto: name ofLenght: len.
name inspect.
I hope this helps.
Best wishes,
Tomaz
