Availability:C-language interface function
const char* PL_atom_chars(atom_t
atom)Deprecated. This function returns a pointer to the content represented
by the atom or blob regardless of its type. New code should use the blob
functions such as PL_blob_data()
to get a pointer to the content, the size of the content, and the type
of the content. Most applications that need to get text from a term_t
handle should use PL_get_nchars()
or PL_get_wchars().
If it is known that atom is a classical Prolog text
atom, one can use PL_atom_nchars()
to obtain the C string and its length (for ISO-Latin-1 atoms) or PL_atom_wchars()
to obtain a C wide string (wchar_t).
