Parameters

[in]	aid	sion API id
[in]	fname	name of file, should be equal on all tasks
[in]	file_mode	like the type parameter of fopen (currently recognized options: "rb", "wb")
[in,out]	chunksize	maximum size to be written with single write call
[in,out]	fsblksize	file system block size (-1 for automatic)
[in]	gcommgroup	global communicator
[in]	grank	global rank of process
[in]	gsize	size of global communicator
[in,out]	filenumber	file number (for multiple file mode)
[in,out]	numfiles	number of files to use (-1 for automatic choosing from local communicator)
[in]	lrank	local rank of process
[in]	lsize	size of local communicator
[in,out]	fileptr	file pointer (NULL for not using an external file pointer)
[out]	newfname	return value for actual file name if using multiple files

Return values

sid	sion file handle or -1 if error occured
