=pod =head1 NAME SSL_CONF_CTX_set1_prefix - Set configuration context command prefix =head1 SYNOPSIS #include <openssl/ssl.h> unsigned int SSL_CONF_CTX_set1_prefix(SSL_CONF_CTX *cctx, const char *prefix); =head1 DESCRIPTION The function SSL_CONF_CTX_set1_prefix() sets the command prefix of B<cctx> to B<prefix>. If B<prefix> is B<NULL> it is restored to the default value. =head1 NOTES Command prefixes alter the commands recognised by subsequent SSL_CONF_cmd() calls. For example for files, if the prefix "SSL" is set then command names such as "SSLProtocol", "SSLOptions" etc. are recognised instead of "Protocol" and "Options". Similarly for command lines if the prefix is "--ssl-" then "--ssl-no_tls1_2" is recognised instead of "-no_tls1_2". If the B<SSL_CONF_FLAG_CMDLINE> flag is set then prefix checks are case sensitive and "-" is the default. In the unlikely even an application explicitly wants to set no prefix it must be explicitly set to "". If the B<SSL_CONF_FLAG_FILE> flag is set then prefix checks are case insensitive and no prefix is the default. =head1 RETURN VALUES SSL_CONF_CTX_set1_prefix() returns 1 for success and 0 for failure. =head1 SEE ALSO L<ssl(7)>, L<SSL_CONF_CTX_new(3)>, L<SSL_CONF_CTX_set_flags(3)>, L<SSL_CONF_CTX_set_ssl_ctx(3)>, L<SSL_CONF_cmd(3)>, L<SSL_CONF_cmd_argv(3)> =head1 HISTORY These functions were added in OpenSSL 1.0.2. =head1 COPYRIGHT Copyright 2012-2016 The OpenSSL Project Authors.
