AnchorName	description

Description:

HTML Wrap

class	hdf-rm-section

H5D_FILL explicitly fills the dataspace selection in memory, space_id, with the fill value specified in fill. If fill is NULL, a fill value of 0 (zero) is used.

fill_type_id specifies the datatype of the fill value.

buf specifies the buffer in which the dataspace elements will be written.

buf_type_id specifies the datatype of those data elements.

Note that if the fill value datatype differs from the memory buffer datatype, the fill value will be converted to the memory buffer datatype before filling the selection.

Note

Applications sometimes write data only to portions of an allocated dataset. It is often useful in such cases to fill the unused space with a known fill value. See the following function for more information:
