The function NF90_INQ_VAR_DEFLATE returns the deflate settings for a
variable in a netCDF-4 file.
Usage
function nf90_inq_var_deflate(ncid, varid, shuffle, deflate, deflate_level)
integer, intent(in) :: ncid
integer, intent(in) :: varid
integer, intent(out) :: shuffle
integer, intent(out) :: deflate
integer, intent(out) :: deflate_level
integer :: nf90_inq_var_deflate
NCID- NetCDF ID, from a previous call to NF90_OPEN or NF90_CREATE.
VARID- Variable ID.

turned on for this variable, and a 0 otherwise.
DEFLATE- NF90_INQ_VAR_DEFLATE will set this to a 1 if the deflate filter is
turned on for this variable, and a 0 otherwise.
