[uses]
SelectorProviderUDT.STREAM.openSocketChannel()
SocketChannel.configureBlocking(false);
SocketChannel.write(buffer);
[problem]
unexpected error message printed out to screen when transport huge data by split 1024bytes
message : 'send: Non-blocking call failure: no buffer available for sending'
my application is console(terminal) application then i hope avoid this message to be printed

[trace]
SocketChannel.write() => SocketUDT.write() => SocketUDT.send() => static native SocketUDT.send1() => api.cpp/CUDT::send((UDTSOCKET u, const char* buf, int len, int)
=> core.cpp/CUDT::send(const char* data, int len)
=> if (m_iSndBufSize <= m_pSndBuffer->getCurrBufSize())
{
if (!m_bSynSending)
throw CUDTException(6, 1, 0);
=> common.cpp/CUDTException::getErrorMessage()
=> case 6:
m_strMsg = "Non-blocking call failure";

    switch (m_iMinor)
    {
    case 1:
       m_strMsg += ": no buffer available for sending";
       break;

[help me]
how can I avoid this error? or is there any way to check UDT buffer space enough?
or disable error message...
at least i want way to get m_iSndBufSize and m_pSndBuffer->getCurrBufSize() at barchart-udt

please help. thank you

i try compile udt and barchart jni but failed to link udt.dll to jni because error 'undefined reference to __im__ZNxxx'
there isn't way to merge msvc dll and g++ or convert dll to .a
-dlltool could not create .a containing dll, .a just offer to interface to use dll from mingw

[solution]

1. modify code conflict pthread...
2. make dllimport define to empty from udt.h
3. compile barchart jni with udt source(not compile udt.dll)
   -use compile option : barchart-udt-core/aol.properties
