ecl_make_keyword Find a lisp keyword cl_object ecl_make_keyword char * name Many Lisp functions take keyword arguments. When invoking a function with keyword arguments we need keywords, which are a kind of symbols that live in the KEYWORD package. This function does the task of finding or creating those keywords from C strings. It is usually safe to store the resulting pointer, because keywords are always referenced by their package and will not be garbage collected (unless of course, you decide to delete it). Remember that the case of the string is significant. ecl_make_keyword("TO") with return :TO, while ecl_make_keyword("to") returns a completely different keywod, :|to|. In short, you usually want to use uppercase. The following example converts a section of a string to uppercase characters: cl_object start = ecl_make_keyword("START"); cl_object end = ecl_make_keyword("END"); ... sup = cl_string_upcase(4, s, start, ecl_make_fixnum(2), end, ecl_make_fixnum(6)); ... ecl_make_symbol Find a lisp symbol cl_object ecl_make_symbol const char * name const char * package_name This function finds or create a symbol in the given package. First of all, it tries to find the package named by package_name. If it does not exist, an error is signaled. Then, a symbol with the suppled name is searched in the given package. If the symbol exists, it is returned. If it does not exist, using INTERN.
