C++ (Cpp) OpenFileForWrite Examples

Example #1

File: processoptions.cpp Project: ClementLeBihan/CelluleFlexible

int ProcessOptions::WriteFile(const char *filename, POVMSObjectPtr obj)
{
	struct INI_Parser_Table *table = parse_ini_table;
	OTextStream *ini_file;
	int err = kNoErr;

	if(!POV_ALLOW_FILE_WRITE(filename, POV_File_Text_INI))
		return kCannotOpenFileErr;

	ini_file = OpenFileForWrite(filename, obj);
	if(ini_file == NULL)
		return kCannotOpenFileErr;
	err = WriteFile (ini_file, obj);
	delete ini_file;

	return err;
}
