Detailed Description

File create and open functions

These functions end up calling functions in one of the dispatch layers (netCDF-4, dap server, etc).

Function Documentation

check_create_mode()

static int check_create_mode ( int  mode )

static

Check the create mode parameter for sanity.

Some create flags cannot be used if corresponding library features are enabled during the build. This function does a pre-check of the mode flag before calling the dispatch layer nc_create functions.

Parameters

mode	The creation mode flag.

Returns

NC_NOERR No error.

NC_ENOTBUILT Requested feature not built into library

NC_EINVAL Invalid combination of modes.

Definition at line 1759 of file dfile.c.

nc_inq_nvars()

int nc_inq_nvars	(	int	ncid,
		int *	nvarsp
	)

Learn the number of variables in a file or group.

Parameters

ncid	File and group ID.
nvarsp	Pointer that gets number of variables. Ignored if NULL.

Returns

NC_NOERR No error.

NC_EBADID Bad ncid.
