10
11 unsigned int SSL_CONF_CTX_set1_prefix(SSL_CONF_CTX *cctx, const char *prefix);
12
13=head1 DESCRIPTION
14
15The function SSL_CONF_CTX_set1_prefix() sets the command prefix of B<cctx>
16to B<prefix>. If B<prefix> is B<NULL> it is restored to the default value.
17
18=head1 NOTES
19
20Command prefixes alter the commands recognised by subsequent SSL_CTX_cmd()
21calls. For example for files, if the prefix "SSL" is set then command names
22such as "SSLProtocol", "SSLOptions" etc. are recognised instead of "Protocol"
23and "Options". Similarly for command lines if the prefix is "--ssl-" then 
24"--ssl-no_tls1_2" is recognised instead of "-no_tls1_2".
25
26If the B<SSL_CONF_FLAG_CMDLINE> flag is set then prefix checks are case
27sensitive and "-" is the default. In the unlikely even an application
28explicitly wants to set no prefix it must be explicitly set to "".
29
30If the B<SSL_CONF_FLAG_FILE> flag is set then prefix checks are case
31insensitive and no prefix is the default.
