Combines a hyperslab selection with the current selection for a dataspace. If the current selection is not a hyperslab, it is freed and the hyperslab parameters passed in are combined with the h5s_SEL_ALL hyperslab (ie. a selection composing the entire current extent). If stride or block is NULL, they are assumed to be set to all '1'.

Parameters:

dsid :: HId_t

Dataspace ID of selection to modify

op :: H5S_seloper_t

Operation to perform on current selection

start :: InArray HSize_t

Offset of start of hyperslab

stride :: InArray HSize_t

h5s_select_elements :: HId_t -> H5S_seloper_t -> CSize -> InArray HSize_t -> IO HErr_t

This function selects array elements to be included in the selection for the dataspace. The coord array is a 2-D array of size <dataspace rank> by num_elem (ie. a list of coordinates in the dataspace). The order of the element coordinates in the coord array specifies the order that the array elements are iterated through when I/O is performed. Duplicate coordinates are not checked for. The selection operator, op, determines how the new selection is to be combined with the existing selection for the dataspace. Currently, only h5s_SELECT_SET is supported, which replaces the existing selection with the one defined in this call. When operators other than h5s_SELECT_SET are used to combine a new selection with an existing selection, the selection ordering is reset to C array ordering.

Parameters:

dsid :: HId_t

Dataspace ID of selection to modify

op :: H5S_seloper_t

Operation to perform on current selection

num_elem :: CSize

Number of elements in COORD array.

h5s_get_select_hyper_blocklist :: HId_t -> HSize_t -> HSize_t -> OutArray HSize_t -> IO HErr_t

Puts a list of the hyperslab blocks into the user's buffer. The blocks start with the startblockth block in the list of blocks and put numblocks number of blocks into the user's buffer (or until the end of the list of blocks, whichever happen first)

The block coordinates have the same dimensionality (rank) as the dataspace they are located within. The list of blocks is formatted as follows: <"start" coordinate> immediately followed by <"opposite" corner coordinate>, followed by the next "start" and "opposite" coordinate, etc. until all the block information requested has been put into the user's buffer.

No guarantee of any order of the blocks is implied.

Parameters:

dsid :: HId_t

Dataspace ID of selection to query

startblock :: HSsize_t

Hyperslab block to start with

numblocks :: HSsize_t

Number of hyperslab blocks to get

buf :: OutArray HSsize_t

h5s_get_select_elem_pointlist :: HId_t -> HSize_t -> HSize_t -> OutArray HSize_t -> IO HErr_t

Puts a list of the element points into the user's buffer. The points start with the startpointth block in the list of points and put numpoints number of points into the user's buffer (or until the end of the list of points, whichever happen first)

The point coordinates have the same dimensionality (rank) as the dataspace they are located within. The list of points is formatted as follows: coordinate followed by the next coordinate, etc. until all the point information in the selection have been put into the user's buffer.

The points are returned in the order they will be interated through when a selection is readwritten fromto disk.

Parameters:

dsid :: HId_t

Dataspace ID of selection to query

startpoint :: HSize_t

Element point to start with

numpoints :: HSize_t

h5s_get_select_bounds :: HId_t -> OutArray HSize_t -> OutArray HSize_t -> IO HErr_t

Retrieves the bounding box containing the current selection and places it into the user's buffers. The start and end buffers must be large enough to hold the dataspace rank number of coordinates. The bounding box exactly contains the selection, ie. if a 2-D element selection is currently defined with the following points: (4,5), (6,8) (10,7), the bounding box with be (4, 5), (10, 8). Calling this function on a "none" selection returns fail.

The bounding box calculations _does_ include the current offset of the selection within the dataspace extent.

Parameters:

dsid :: HId_t

Dataspace ID of selection to query

start :: OutArray HSize_t

Starting coordinate of bounding box

end :: OutArray HSize_t

Opposite coordinate of bounding box

Returns non-negative on success, negative on failure.

Weird warning in source: This routine participates in the "Inlining C function pointers" pattern, don't call it directly, use the appropriate macro defined in H5Sprivate.h.

h5s_encode1 :: HId_t -> OutArray CChar -> InOut CSize -> IO HErr_t

Given a dataspace ID, converts the object description (including selection) into binary in a buffer.

nalloc is the size of the buffer on input, the size of the encoded data on output. If the buffer is not big enough, no data is written to it (but nalloc is still updated with the size needed).

Returns non-negative on success, negative on failure.
