NAME
     X509_get_subject_name, X509_set_subject_name, X509_get_issuer_name,
     X509_set_issuer_name, X509_REQ_get_subject_name,
     X509_REQ_set_subject_name, X509_CRL_get_issuer, X509_CRL_set_issuer_name
     - get and set issuer or subject names

SYNOPSIS
     #include <openssl/x509.h>

     X509_NAME *
     X509_get_subject_name(const X509 *x);

     int
     X509_set_subject_name(X509 *x, X509_NAME *name);

     X509_NAME *
     X509_get_issuer_name(const X509 *x);

     int
     X509_set_issuer_name(X509 *x, X509_NAME *name);

     X509_NAME *
     X509_REQ_get_subject_name(const X509_REQ *req);

     int
     X509_REQ_set_subject_name(X509_REQ *req, X509_NAME *name);

     X509_NAME *
     X509_CRL_get_issuer(const X509_CRL *crl);

     int
     X509_CRL_set_issuer_name(X509_CRL *x, X509_NAME *name);

DESCRIPTION
     X509_get_subject_name() returns the subject name of certificate x.  The
     returned value is an internal pointer which must not be freed.

     X509_set_subject_name() sets the issuer name of certificate x to name.
     The name parameter is copied internally and should be freed up when it is
     no longer needed.

     X509_get_issuer_name() and X509_set_issuer_name() are identical to
     X509_get_subject_name() and X509_set_subject_name() except that they get
     and set the issuer name of x.

     Similarly X509_REQ_get_subject_name(), X509_REQ_set_subject_name(),
     X509_CRL_get_issuer(), and X509_CRL_set_issuer_name() get or set the
     subject or issuer names of certificate requests of CRLs, respectively.

RETURN VALUES
     X509_get_subject_name(), X509_get_issuer_name(),
     X509_REQ_get_subject_name(), and X509_CRL_get_issuer() return a pointer
     to an X509_NAME object.

     X509_set_subject_name(), X509_set_issuer_name(),
     X509_REQ_set_subject_name(), and X509_CRL_set_issuer_name() return 1 for
     success or 0 for failure.  In some cases of failure, the reason can be
     determined with ERR_get_error(3).
