SSL_LOAD_CLIENT_CA_FILE(3)	    OpenSSL	    SSL_LOAD_CLIENT_CA_FILE(3)

NAME
       SSL_load_client_CA_file - load certificate names	from file

SYNOPSIS
	#include <openssl/ssl.h>

	STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char	*file);

DESCRIPTION
       SSL_load_client_CA_file() reads certificates from file and returns a
       STACK_OF(X509_NAME) with	the subject names found.

NOTES
       SSL_load_client_CA_file() 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.

EXAMPLES
       Load names of CAs from file and use it as a client CA list:

	SSL_CTX	*ctx;
	STACK_OF(X509_NAME) *cert_names;

	...
	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 */
	...

RETURN VALUES
       The following return values can occur:

       NULL
	   The operation failed, check out the error stack for the reason.

       Pointer to STACK_OF(X509_NAME)
	   Pointer to the subject names	of the successfully read certificates.
