Availability:C-language interface function

int PL_free_blob(atom_t blob)

New in 9.1.12. This function may be used on blobs with the PL_BLOB_NOCOPY flag set and a release() function. It causes the release() function to be called, after which the data and size are set to 0. The related atom remains existent and accessing it as a blob returns NULL for the data and 0 for the size.
