Re: [xml] xmlOutputBufferCreateFile VS2015 I/O error : Bad file descriptor
Hello,
It works if I link (statically) to libxml2_a_dll.lib or libxml2_a.lib
what is the difference between the two libs?
for reference I compile libxml this way:
cscript.exe configure.js iconv=no ftp=no http=no compiler=msvc cruntime=/MT
debug=yes prefix="build_debug_static_mt" static=yes
I am not sure about the flag static=yes... it seems there is no effect, do
you confirm?
additionally I removed iconv (iconv=no), do you confirm that reading UTF-8
and UTF-16 will still work?
do you have any idea why the dynamic linking is not working?
Best regards,
Sylvain

Hello,
porting my program on windows, I noticed that xmlOutputBufferCreateFile

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

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?

Re: [xml] xmlOutputBufferCreateFile VS2015 I/O error : Bad file descriptor
Hello,
it also fails when creating the FILE *f = (FILE*) xmlFileOpen(
"C:\\test_data\\testxml.xml");
or using the file descriptor:
int fd = _open("C:\\test_data\\testxml.xml", _O_CREAT | _O_RDWR);
xmlOutputBufferPtr output = xmlOutputBufferCreateFd(fd, NULL);
Does anyone have an idea on where the issue could be?

Actually I made the mistake to replace the path at the last minute for the
email, but the path was correct in my test program. I really don't
understand where the issue could be...

Not sure if it's important, but I see that internally libxml2 opens with
"wb" mode in some cases.

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++

Re: [xml] xmlOutputBufferCreateFile VS2015 I/O error : Bad file descriptor
Hello,
using
xmlOutputBufferPtr output = xmlOutputBufferCreateFilename("C
:\\myfolder\testdata.xml", 0, 0);
works...
what can be wrong with xmlOutputBufferCreateFile?
