.SH NAME
SSL_CTX_set_default_ctlog_list_file, SSL_CTX_set_ctlog_list_file \-
load a Certificate Transparency log list from a file
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/ssl.h>

.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBSSL_CTX_set_default_ctlog_list_file()\fR 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.
.PP
\&\fBSSL_CTX_set_ctlog_list_file()\fR loads a list of CT logs from a specific path.
See \fBCTLOG_STORE_new\fR\|(3) for the file format.
.SH NOTES
.IX Header "NOTES"
These functions will not clear the existing CT log list \- it will be appended
to. To replace the existing list, use \fBSSL_CTX_set0_ctlog_store\fR\|(3) first.
.PP
If an error occurs whilst parsing a particular log entry in the file, that log
entry will be skipped.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBSSL_CTX_set_default_ctlog_list_file()\fR and \fBSSL_CTX_set_ctlog_list_file()\fR
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.
