SSL_CONF_CTX_set1_prefix(3)         OpenSSL        SSL_CONF_CTX_set1_prefix(3)

       SSL_CONF_CTX_set1_prefix - Set configuration context command prefix

       libcrypto, -lcrypto

        #include <openssl/ssl.h>

        unsigned int SSL_CONF_CTX_set1_prefix(SSL_CONF_CTX *cctx, const char *prefix);

       The function SSL_CONF_CTX_set1_prefix() sets the command prefix of cctx
       to prefix. If prefix is NULL it is restored to the default value.

       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 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 SSL_CONF_FLAG_FILE flag is set then prefix checks are case
       insensitive and no prefix is the default.

       SSL_CONF_CTX_set1_prefix() returns 1 for success and 0 for failure.
