       odbx_lo_write - Writes buffer content into the large object


       #include <opendbx/api.h>

       ssize_t odbx_lo_write (odbx_lo_t* lo, void* buffer, size_t buflen);


       odbx_lo_write()  sends the data supplied in buffer to the server for storing it inside the
       large object. The function can be called more than once to add  subsequent  parts  of  the
       content  to  the  object.  If  it  isn't  a new or empty object, the existing data will be
       overwritten and truncated to the new size. It's not possible to update only parts  of  the
       content  as  some  databases  doesn't  support  to  position  the  internal  file position

       The lo parameter has to be the large object handle created and returned by  odbx_lo_open()
       via  its second parameter. It becomes invalid after it was supplied to odbx_lo_close() and
       this function will return an error in this case. The data which  should  be  send  to  the
       server is read from buffer up to buflen bytes.


       odbx_lo_write()  returns  the  number  of  bytes read from buffer and sent to the database
       server, which may be up to buflen bytes. It isn't guaranteed that the complete  chunk  was
       sent to the server, so the returned size may be less than the value in buflen. On error, a
       code whose value is less than zero is returned  if  one  of  the  operations  couldn't  be
       completed  successfully. Possible error codes are listed in the error section and they can
       be feed to odbx_error() and odbx_error_type() to get further details.


              The native database library couldn't write to the large object successfully

              lo is NULL or the supplied large object handle is invalid
