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.
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.
The following return values can occur:
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 */
