SSL_CONF_CTX_set1_prefix - Set configuration context command prefix
#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.
