Re: [xml] xmlOutputBufferCreateFile VS2015 I/O error : Bad file descriptor

hello again,

I investigated a bit more with my own compiled libxml2 in debug mode, the stack trace is:

  libxml2.dll!_invalid_parameter(const wchar_t * const _expression_, const wchar_t * const function_name, const wchar_t * const file_name, const unsigned int line_number, const unsigned int reserved) Line 91 C++
  libxml2.dll!_invalid_parameter_noinfo() Line 97 C++
  libxml2.dll!_write(int fh, const void * buffer, unsigned int size) Line 48 C++
> libxml2.dll!__acrt_stdio_flush_nolock(_iobuf * public_stream) Line 152 C++
  libxml2.dll!_fflush_nolock(_iobuf * public_stream) Line 114 C++
  libxml2.dll!fflush(_iobuf * stream) Line 94 C++
  libxml2.dll!xmlFileFlush(void * context) Line 1104 C
  libxml2.dll!xmlOutputBufferClose(_xmlOutputBuffer * out) Line 2606 C

Best regards,

what can be wrong with xmlOutputBufferCreateFile?

porting my program on windows, I noticed that xmlOutputBufferCreateFile raised a message  I/O error : Bad file descriptor. Below is the sample program that crashes for me:

FILE *f = fopen("C:\\myfolder\testdata.xml", "w");

xmlOutputBufferPtr output = xmlOutputBufferCreateFile(f, NULL);

xmlOutputBufferWriteString(output, "WHY DO YOU CRASH?");

xmlOutputBufferClose(output); <- at this moment it displays I/O error : Bad file descriptor


I linked on libs pre-compiled for win32,
I also tried with the lib I compiled myself, it even crashes in this case (it does not display IO error)

Please note that the parsing (SAX) runs well.

Do you have any idea? is it a bug or something I am not doing well?
