Function Documentation

PIOc_inq_att()

int PIOc_inq_att	(	int	ncid,
		int	varid,
		const char *	name,
		nc_type *	xtypep,
		PIO_Offset *	lenp
	)

The PIO-C interface for the NetCDF function nc_inq_att.

This routine is called collectively by all tasks in the communicator ios.union_comm. For more information on the underlying NetCDF commmand please read about this function in the NetCDF documentation at: http://www.unidata.ucar.edu/software/netcdf/docs/group__attributes.html

Parameters

ncid	the ncid of the open file, obtained from PIOc_openfile() or PIOc_createfile().
varid	the variable ID or NC_GLOBAL.
name	name of the attribute.
xtypep	a pointer that will get the type of the attribute.
lenp	a pointer that will get the number of values

Returns

PIO_NOERR for success, error code otherwise.

PIOc_inq_att_eh()

int PIOc_inq_att_eh	(	int	ncid,
		int	varid,
		const char *	name,
		int	eh,
		nc_type *	xtypep,
		PIO_Offset *	lenp
	)

The PIO-C interface for the NetCDF function nc_inq_att.

This routine is called collectively by all tasks in the communicator ios.union_comm. For more information on the underlying NetCDF commmand please read about this function in the NetCDF documentation at: http://www.unidata.ucar.edu/software/netcdf/docs/group__attributes.html

ncid	the ncid of the open file, obtained from PIOc_openfile() or PIOc_createfile().
varid	the variable ID or NC_GLOBAL.
name	name of the attribute.
eh	non-zero to handle errors in the function. This will cause program to halt if PIO error handler is set to INTERNAL.
