NAME

       SSL_CTX_set_default_ctlog_list_file, SSL_CTX_set_ctlog_list_file - load a Certificate Transparency log
       list from a file

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_CTX_set_default_ctlog_list_file(SSL_CTX *ctx);
        int SSL_CTX_set_ctlog_list_file(SSL_CTX *ctx, const char *path);

DESCRIPTION

       SSL_CTX_set_default_ctlog_list_file() loads a list of Certificate Transparency (CT) logs from the default
       file location, "ct_log_list.cnf", found in the directory where OpenSSL is installed.

       SSL_CTX_set_ctlog_list_file() loads a list of CT logs from a specific path.  See CTLOG_STORE_new(3) for
       the file format.

NOTES

       These functions will not clear the existing CT log list - it will be appended to. To replace the existing
       list, use SSL_CTX_set0_ctlog_store(3) first.

       If an error occurs whilst parsing a particular log entry in the file, that log entry will be skipped.

RETURN VALUES

       SSL_CTX_set_default_ctlog_list_file() and SSL_CTX_set_ctlog_list_file() return 1 if the log list is
       successfully loaded, and 0 if an error occurs. In the case of an error, the log list may have been
       partially loaded.
