Reclaims variable-length (VL) datatype memory buffers (DEPRECATED)

This function has been deprecated in favor of the function H5T_RECLAIM.

H5D_VLEN_RECLAIM(type_id, space_id, plist_id, buf)


Edit each block below with the corresponding language signature for this function.

H5D_VLEN_RECLAIM reclaims memory buffers created to store VL datatypes.

The type_id must be the datatype stored in the buffer. The space_id describes the selection for the memory buffer to free the VL datatypes within. The plist_id is the dataset transfer property list which was used for the I/O transfer to create the buffer. And buf is the pointer to the buffer to be reclaimed.

The VL structures (hvl_t) in the user's buffer are modified to zero out the VL information after the memory has been reclaimed.

If nested VL datatypes were used to create the buffer, this routine frees them from the bottom up, releasing all the memory without creating memory leaks.

Returns non-negative value if successful; otherwise returns a negative value.
