+.SH NAME
+OPENSSL_config, OPENSSL_no_config \- simple OpenSSL configuration functions
+.SH SYNOPSIS
+.IX Header "SYNOPSIS"
+.Vb 1
+\& #include <openssl/conf.h>
+.Ve
+.PP
+The following functions have been deprecated since OpenSSL 1.1.0, and can be
+hidden entirely by defining \fBOPENSSL_API_COMPAT\fR with a suitable version value,
+see \fBopenssl_user_macros\fR\|(7):
+.PP
+.Vb 2
+\& void OPENSSL_config(const char *appname);
+\& void OPENSSL_no_config(void);
+.Ve
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBOPENSSL_config()\fR configures OpenSSL using the standard \fBopenssl.cnf\fR and
+reads from the application section \fBappname\fR. If \fBappname\fR is NULL then
+the default section, \fBopenssl_conf\fR, will be used.
+Errors are silently ignored.
+Multiple calls have no effect.
+.PP
+\&\fBOPENSSL_no_config()\fR disables configuration. If called before \fBOPENSSL_config()\fR
+no configuration takes place.
+.PP
+If the application is built with \fBOPENSSL_LOAD_CONF\fR defined, then a
+call to \fBOpenSSL_add_all_algorithms()\fR will implicitly call \fBOPENSSL_config()\fR
+first.
+.SH NOTES
+.IX Header "NOTES"
+The \fBOPENSSL_config()\fR function is designed to be a very simple "call it and
+forget it" function.
+It is however \fBmuch\fR better than nothing. Applications which need finer
+control over their configuration functionality should use the configuration
+functions such as \fBCONF_modules_load()\fR directly. This function is deprecated
+and its use should be avoided.
+Applications should instead call \fBCONF_modules_load()\fR during
+initialization (that is before starting any threads).
+.PP
+There are several reasons why calling the OpenSSL configuration routines is
+advisable. For example, 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 \fBOPENSSL_config()\fR it doesn't need to know or care about
+ENGINE control operations because they can be performed by editing a
+configuration file.
+.SH ENVIRONMENT
+.IX Header "ENVIRONMENT"
+.IP \fBOPENSSL_CONF\fR 4
+.IX Item "OPENSSL_CONF"
+The path to the config file.
+Ignored in set-user-ID and set-group-ID programs.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+Neither \fBOPENSSL_config()\fR nor \fBOPENSSL_no_config()\fR return a value.
+.SH "SEE ALSO"
+.IX Header "SEE ALSO"
+\&\fBconfig\fR\|(5),
+\&\fBCONF_modules_load_file\fR\|(3)
+.SH HISTORY
+.IX Header "HISTORY"
+The \fBOPENSSL_no_config()\fR and \fBOPENSSL_config()\fR functions were
+deprecated in OpenSSL 1.1.0 by \fBOPENSSL_init_crypto()\fR.
