If B<config_name> is NULL then +the default name B<openssl_conf> will be used. Any errors are ignored. Further +calls to OPENSSL_config() will have no effect. The configuration file format +is documented in the L<conf(5)|conf(5)> manual page. + +OPENSSL_no_config() disables configuration. If called before OPENSSL_config() +no configuration takes place. + +=head1 NOTES + +It is B<strongly> recommended that B<all> new applications call OPENSSL_config() +or the more sophisticated functions such as CONF_modules_load() during +initialization (that is before starting any threads). By doing this +an application does not need to keep track of all configuration options +and some new functionality can be supported automatically. + +It is also possible to automatically call OPENSSL_config() when an application +calls OPENSSL_add_all_algorithms() by compiling an application with the +preprocessor symbol B<OPENSSL_LOAD_CONF> #define'd. In this way configuration +can be added without source changes. + +The environment variable B<OPENSSL_CONF> can be set to specify the location +of the configuration file. + +Currently ASN1 OBJECTs and ENGINE configuration can be performed future +versions of OpenSSL will add new configuration options. + +There are several reasons why calling the OpenSSL configuration routines is +advisable. For example new ENGINE functionality was added to OpenSSL 0.9.7. +In OpenSSL 0.9.7 control functions can be supported by ENGINEs, this can be +used (among other things) to load dynamic ENGINEs from shared libraries (DSOs). +However very few applications currently support the control interface and so +very few can load and use dynamic ENGINEs. Equally in future more sophisticated +ENGINEs will require certain control operations to customize them. If an +application calls OPENSSL_config() it doesn't need to know or care about +ENGINE control operations because they can be performed by editing a +configuration file. + +Applications should free up configuration at application closedown by calling +CONF_modules_free(). + +=head1 RESTRICTIONS + +The OPENSSL_config() function is designed to be a very simple "call it and +forget it" function. As a result its behaviour is somewhat limited. It ignores +all errors silently and it can only load from the standard configuration file +location for example. + +It is however B<much> better than nothing. Applications which need finer +control over their configuration functionality should use the configuration +functions such as CONF_load_modules() directly. + +=head1 RETURN VALUES + +Neither OPENSSL_config() nor OPENSSL_no_config() return a value. + +=head1 SEE ALSO + +L<conf(5)|conf(5)>, L<CONF_load_modules_file(3)|CONF_load_modules_file(3)>, +L<CONF_modules_free(3),CONF_modules_free(3)> + +=head1 HISTORY + +OPENSSL_config() and OPENSSL_no_config() first appeared in OpenSSL 0.9.7 + +=cut |
