Detailed Description

The netCDF-4 file functions.

This file is part of netcdf-4, a netCDF-like interface for HDF5, or a HDF5 backend for netCDF, depending on your point of view.

Definition in file nc4file.c.

Function Documentation

int NC4_create	(	const char *	path,
		int	cmode,
		size_t	initialsz,
		int	basepe,
		size_t *	chunksizehintp,
		int	use_parallel,
		void *	mpidata,
		NC_Dispatch *	dispatch,
		NC *	nc_file
	)

Create a netCDF-4/HDF5 file.

Parameters:

path	The file name of the new file.
cmode	The creation mode flag.
initialsz	Ignored by this function.
basepe	Ignored by this function.
chunksizehintp	Ignored by this function.
use_parallel	0 for sequential, non-zero for parallel I/O.
mpidata	pointer to struct holdind data for parallel I/O layer. Ignored if NULL.
dispatch	Pointer to the dispatch table for this file.
nc_file	Pointer to an instance of NC.

Returns:: NC_INVAL Invalid input (check cmode).
