If the method table 33I<meth> is set to NULL then the default value of NCONF_default() is used. 34 35NCONF_new() is similar to NCONF_new_ex() but sets the I<libctx> to NULL. 36 37NCONF_free() frees the data associated with I<conf> and then frees the I<conf> 38object. 39 40NCONF_load() parses the file named I<filename> and adds the values found to 41I<conf>. If an error occurs I<file> and I<eline> list the file and line that 42the load failed on if they are not NULL. 43 44NCONF_default() gets the default method table for processing a configuration file. 45 46NCONF_get0_libctx() gets the library context associated with the I<conf> 47parameter. 48 49NCONF_get_section_names() gets the names of the sections associated with 50the I<conf> as B<STACK_OF(OPENSSL_CSTRING)> strings. The individual strings 51are associated with the I<conf> and will be invalid after I<conf> is 52freed. The returned stack must be freed with sk_OPENSSL_CSTRING_free(). 53 54NCONF_get_section() gets the config values associated with the I<conf> from 55the config section I<name> as B<STACK_OF(CONF_VALUE)> structures. The returned 56stack is associated with the I<conf> and will be invalid after I<conf> 57is freed. It must not be freed by the caller. 58 59=head1 RETURN VALUES 60 61NCONF_load() returns 1 on success or 0 on error. 62 63NCONF_new_ex() and NCONF_new() return a newly created I<CONF> object 64or NULL if an error occurs. 65 66=head1 SEE ALSO 67 68L<CONF_modules_load_file(3)>, 69 70=head1 HISTORY 71 72NCONF_new_ex(), NCONF_get0_libctx(), and NCONF_get_section_names() were added 73in OpenSSL 3.0. 74 75=head1 COPYRIGHT 76 77Copyright 2020-2021 The OpenSSL Project Authors.
