.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBOSSL_LIB_CTX_set_conf_diagnostics()\fR sets the value of the configuration
diagnostics flag. If \fIvalue\fR is nonzero subsequent parsing and application
of configuration data can report errors that would otherwise be ignored. In
particular any errors in the ssl configuration module will cause a failure
of \fBSSL_CTX_new\fR\|(3) and \fBSSL_CTX_new_ex\fR\|(3) calls. The configuration
diagnostics flag can be also set when a configuration file is being loaded
into \fB\s-1OSSL_LIB_CTX\s0\fR with \fBOSSL_LIB_CTX_load_config\fR\|(3). If the configuration
sets a \fBconfig_diagnostics\fR value as described in \fBconfig\fR\|(5), it will
override the value set by \fBOSSL_LIB_CTX_set_conf_diagnostics()\fR before
loading the configuration file.
.PP
\&\fBOSSL_LIB_CTX_get_conf_diagnostics()\fR returns the current value of the
configuration diagnostics flag.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOSSL_LIB_CTX_get_conf_diagnostics()\fR returns 0 if the configuration diagnostics
should not be performed, nonzero otherwise.
