Availability:C-language interface function
const char* PL_atom_chars(atom_t
atom)Return a C-string for the text represented by the given atom. The
returned text will not be changed by Prolog. It is not allowed to modify
the contents, not even‘temporary' as the string may reside in
read-only memory. The returned string becomes invalid if the atom is
garbage collected (see section
12.4.2.1). Foreign functions that require the text from an atom
passed in a term_t normally use
PL_get_atom_chars()
or PL_get_atom_nchars().
