.SH "NAME"
SSL_load_client_CA_file \- load certificate names from file
.SH "SYNOPSIS"
.PP
.Vb 1
\& #include <openssl/ssl.h>
.Ve
.Vb 1
\& STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);
.Ve
.SH "DESCRIPTION"
\fISSL_load_client_CA_file()\fR reads certificates from \fBfile\fR and returns
a \fISTACK_OF\fR\|(X509_NAME) with the subject names found.
.SH "NOTES"
\fISSL_load_client_CA_file()\fR reads a file of PEM formatted certificates and
extracts the X509_NAMES of the certificates found. While the name suggests
the specific usage as support function for
SSL_CTX_set_client_CA_list(3),
it is not limited to CA certificates.
.SH "EXAMPLES"
Load names of CAs from file and use it as a client CA list:
.PP
.Vb 2
\& SSL_CTX *ctx;
\& STACK_OF(X509_NAME) *cert_names;
.Ve
.Vb 7
\& ... 
\& cert_names = SSL_load_client_CA_file("/path/to/CAfile.pem");
\& if (cert_names != NULL)
\&   SSL_CTX_set_client_CA_list(ctx, cert_names);
\& else
\&   error_handling();
\& ...
.Ve
.SH "RETURN VALUES"
The following return values can occur:
.Ip "\s-1NULL\s0" 4
The operation failed, check out the error stack for the reason.
.Ip "Pointer to \s-1STACK_OF\s0(X509_NAME)" 4
Pointer to the subject names of the successfully read certificates.
.SH "SEE ALSO"
