attached code is how ogre open file for r/w.
Code: Select all
DataStreamPtr FileSystemArchive::open(const String& filename) const
{
String full_path = concatenate_path(mName, filename);
// Use filesystem to determine size
// (quicker than streaming to the end and back)
struct stat tagStat;
int ret = stat(full_path.c_str(), &tagStat);
assert(ret == 0 && "Problem getting file size" );
// Always open in binary mode
std::ifstream *origStream = OGRE_NEW_T(std::ifstream, MEMCATEGORY_GENERAL)();
origStream->open(full_path.c_str(), std::ios::in | std::ios::binary);
// Should check ensure open succeeded, in case fail for some reason.
if (origStream->fail())
{
OGRE_DELETE_T(origStream, basic_ifstream, MEMCATEGORY_GENERAL);
OGRE_EXCEPT(Exception::ERR_FILE_NOT_FOUND,
"Cannot open file: " + filename,
"FileSystemArchive::open");
}
/// Construct return stream, tell it to delete on destroy
FileStreamDataStream* stream = OGRE_NEW FileStreamDataStream(filename,
origStream, tagStat.st_size, true);
return DataStreamPtr(stream);
}
Code: Select all
std::locale saveLocal = std::locale::global(std::locale(""));
origStream->open(full_path.c_str(), std::ios::in | std::ios::binary);
std::locale::global(saveLocal);
any advice?
