/**
@ingroup variables
@internal Get the number of record dimensions for a variable and an
array that identifies which of a variable's dimensions are record
dimensions. Intended to be used instead of NC_is_recvar(), which
doesn't work for netCDF-4 variables which have multiple unlimited
dimensions or an unlimited dimension that is not the first of a
variable's dimensions.
@param ncid File ID.
@param varid Variable ID.
@param nrecdimsp Pointer that gets number of record dims.
@param is_recdim Pointer that gets 1 if there is one or more record
dimensions, 0 if not.
@returns 0 if not a record var, 1 if it is.
Example use:
@code
int nrecdims;
int is_recdim[NC_MAX_VAR_DIMS];
...
status = NC_inq_recvar(ncid,varid,&nrecdims,is_recdim);
isrecvar = (nrecdims > 0);
