Searches for a symbol, by name, in the specified symbol table. If the symbol does not exist, creates the symbol as specified. Returns a SYMBOL pointer to the existing or new symbol, or NULL if a new symbol could not be created. The lookup and creation follow the same rules as sym lookup symbol() and sym create symbol(). The symbol's value is set to the supplied value in all cases. Do not call this function directly; pass through the sym_assume_symbol macro.

Source Code - (sflsymb.c)

        *symbol;                        /*  Allocated or found symbol        */

    ASSERT (table);

    symbol = sym lookup symbol (table, name);
    if (symbol)
        /*  Update the symbol value, if it has changed                       */
        if (symbol-> value && strneq (symbol-> value, value))
            sym set value (symbol, value);
        symbol = sym create symbol  (table, name, value, filename, lineno);

    return (symbol);
