NAME
       SSL_load_client_CA_file, SSL_add_file_cert_subjects_to_stack,
       SSL_add_dir_cert_subjects_to_stack - load certificate names
SYNOPSIS
        #include <openssl/ssl.h>
        STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);
        int SSL_add_file_cert_subjects_to_stack(STACK_OF(X509_NAME) *stack,
                                                const char *file)
        int SSL_add_dir_cert_subjects_to_stack(STACK_OF(X509_NAME) *stack,
                                               const char *dir)
DESCRIPTION
       SSL_load_client_CA_file() reads certificates from file and returns a
       STACK_OF(X509_NAME) with the subject names found.
       SSL_add_file_cert_subjects_to_stack() reads certificates from file, and
       adds their subject name to the already existing stack.
       SSL_add_dir_cert_subjects_to_stack() reads certificates from every file
       in the directory dir, and adds their subject name to the already
       existing stack.
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.
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.
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 */
        ...
