nc_get_var_slab_2d Subroutine

public subroutine nc_get_var_slab_2d(ncid, varid, start, count, data, ierr)

Windowed read of a 2D variable: start/count (length 2, FORTRAN dimension order) select the block that lands in data, whose shape must equal count. The per-rank readers (bathymetry, supergrid) use it to load only the rows their tile needs.

Arguments

Type IntentOptional Attributes Name
integer, intent(in) :: ncid
integer, intent(in) :: varid
integer, intent(in) :: start(2)
integer, intent(in) :: count(2)
real(kind=wp), intent(inout) :: data(:,:)
integer, intent(out), optional :: ierr

Non-zero on failure when present; absent behaves as today (error stop).
