=head1 NAME

SSL_CONF_CTX_set_flags, SSL_CONF_CTX_clear_flags - Set of clear SSL configuration context flags

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 unsigned int SSL_CONF_CTX_set_flags(SSL_CONF_CTX *cctx, unsigned int flags);
 unsigned int SSL_CONF_CTX_clear_flags(SSL_CONF_CTX *cctx, unsigned int flags);

=head1 DESCRIPTION

The function SSL_CONF_CTX_set_flags() sets B<flags> in the context B<cctx>.

The function SSL_CONF_CTX_clear_flags() clears B<flags> in the context B<cctx>.

=head1 NOTES

The flags set affect how subsequent calls to SSL_CONF_cmd() or
SSL_CONF_argv() behave.

Currently the following B<flags> values are recognised:

=over 4

=item SSL_CONF_FLAG_CMDLINE, SSL_CONF_FLAG_FILE

recognise options intended for command line or configuration file use. At
least one of these flags must be set.

=item SSL_CONF_FLAG_CLIENT, SSL_CONF_FLAG_SERVER

recognise options intended for use in SSL/TLS clients or servers. One or
both of these flags must be set.

=item SSL_CONF_FLAG_CERTIFICATE

recognise certificate and private key options.

=item SSL_CONF_FLAG_REQUIRE_PRIVATE

If this option is set then if a private key is not specified for a certificate
it will attempt to load a private key from the certificate file when
SSL_CONF_CTX_finish() is called. If a key cannot be loaded from the certificate
file an error occurs.

=item SSL_CONF_FLAG_SHOW_ERRORS

indicate errors relating to unrecognised options or missing arguments in
the error queue. If this option isn't set such errors are only reflected
in the return values of SSL_CONF_set_cmd() or SSL_CONF_set_argv()

=back

=head1 RETURN VALUES

SSL_CONF_CTX_set_flags() and SSL_CONF_CTX_clear_flags() returns the new flags
value after setting or clearing flags.
