NAME
- H5S_get_vector_size
- PURPOSE
- Gets the size of the I/O vector
- USAGE
- ssize_t H5S_get_vector_size(dxpl_id)
- hid_t dxpl_id; IN: The dataset transfer property list to query
- RETURNS
- Non-negative number of entries in I/O vector on success, negative on failure
- DESCRIPTION
- Retrieves the number of I/O vector entries to use for a given dataset
- transfer. If the default dataset property list is used, the default
- number of I/O vectors is returned.
- GLOBAL VARIABLES
- COMMENTS, BUGS, ASSUMPTIONS
