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 certifi-
       cates 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_handling();
        ...

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.
