If \fBconfig_name\fR is \s-1NULL\s0 then +the default name \fBopenssl_conf\fR will be used. Any errors are ignored. Further +calls to \fIOPENSSL_config()\fR will have no effect. The configuration file format +is documented in the conf(5) manual page. +.PP +\&\fIOPENSSL_no_config()\fR disables configuration. If called before \fIOPENSSL_config()\fR +no configuration takes place. +.SH "NOTES" +.IX Header "NOTES" +It is \fBstrongly\fR recommended that \fBall\fR new applications call \fIOPENSSL_config()\fR +or the more sophisticated functions such as \fICONF_modules_load()\fR 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. +.PP +It is also possible to automatically call \fIOPENSSL_config()\fR when an application +calls \fIOPENSSL_add_all_algorithms()\fR by compiling an application with the +preprocessor symbol \fB\s-1OPENSSL_LOAD_CONF\s0\fR #define'd. In this way configuration +can be added without source changes. +.PP +The environment variable \fB\s-1OPENSSL_CONFIG\s0\fR can be set to specify the location +of the configuration file. +.PP +Currently \s-1ASN1\s0 OBJECTs and \s-1ENGINE\s0 configuration can be performed future +versions of OpenSSL will add new configuration options. +.PP +There are several reasons why calling the OpenSSL configuration routines is +advisable. For example new \s-1ENGINE\s0 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 \fIOPENSSL_config()\fR it doesn't need to know or care about +\&\s-1ENGINE\s0 control operations because they can be performed by editing a +configuration file. +.PP +Applications should free up configuration at application closedown by calling +\&\fICONF_modules_free()\fR. +.SH "RESTRICTIONS" +.IX Header "RESTRICTIONS" +The \fIOPENSSL_config()\fR function is designed to be a very simple \*(L"call it and +forget it\*(R" 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. +.PP +It is however \fBmuch\fR better than nothing. Applications which need finer +control over their configuration functionality should use the configuration +functions such as \fICONF_load_modules()\fR directly. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +Neither \fIOPENSSL_config()\fR nor \fIOPENSSL_no_config()\fR return a value. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +conf(5), CONF_load_modules_file(3), +\&\fICONF_modules_free\fR\|(3),CONF_modules_free(3) +.SH "HISTORY" +.IX Header "HISTORY" +\&\fIOPENSSL_config()\fR and \fIOPENSSL_no_config()\fR first appeared in OpenSSL 0.9.7 |
