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().
