=head1 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

=head1 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);

=head1 DESCRIPTION

X509_get_subject_name() returns the subject name of certificate B<x>. The
returned value is an internal pointer which B<MUST NOT> be freed.

X509_set_subject_name() sets the issuer name of certificate B<x> to
B<name>. The B<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 the get and
set the issuer name of B<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.

=head1 RETURN VALUES

X509_get_subject_name(), X509_get_issuer_name(), X509_REQ_get_subject_name()
and X509_CRL_get_issuer() return an B<X509_NAME> pointer.

X509_set_subject_name(), X509_set_issuer_name(), X509_REQ_set_subject_name()
and X509_CRL_set_issuer_name() return 1 for success and 0 for failure.
