The returned value is an internal pointer which must not be freed. .Pp .Fn X509_set_subject_name sets the issuer name of certificate .Fa x to .Fa name . The .Fa name parameter is copied internally and should be freed up when it is no longer needed. .Pp .Fn X509_get_issuer_name and .Fn X509_set_issuer_name are identical to .Fn X509_get_subject_name and .Fn X509_set_subject_name except that they get and set the issuer name of .Fa x . .Pp Similarly .Fn X509_REQ_get_subject_name , .Fn X509_REQ_set_subject_name , .Fn X509_CRL_get_issuer , and .Fn X509_CRL_set_issuer_name get or set the subject or issuer names of certificate requests of CRLs, respectively. .Pp .Fn X509_REQ_get_subject_name and .Fn X509_CRL_get_issuer are implemented as macros. .Sh RETURN VALUES .Fn X509_get_subject_name , .Fn X509_get_issuer_name , .Fn X509_REQ_get_subject_name , and .Fn X509_CRL_get_issuer return a pointer to an .Vt X509_NAME object. .Pp .Fn X509_set_subject_name , .Fn X509_set_issuer_name , .Fn X509_REQ_set_subject_name , and .Fn X509_CRL_set_issuer_name return 1 for success or 0 for failure. In some cases of failure, the reason can be determined with .Xr ERR_get_error 3 . .Sh SEE ALSO .Xr d2i_X509_NAME 3 , .Xr X509_CRL_get0_by_serial 3 , .Xr X509_CRL_new 3 , .Xr X509_get_pubkey 3 , .Xr X509_NAME_add_entry_by_txt 3 , .Xr X509_NAME_ENTRY_get_object 3 , .Xr X509_NAME_get_index_by_NID 3 , .Xr X509_NAME_new 3 , .Xr X509_NAME_print_ex 3 , .Xr X509_new 3 , .Xr X509_REQ_new 3 , .Xr X509_sign 3 , .Xr X509_verify_cert 3 , .Xr X509V3_get_d2i 3 .Sh HISTORY .Fn X509_get_subject_name and .Fn X509_get_issuer_name appeared in SSLeay 0.4 or earlier. .Fn X509_set_subject_name , .Fn X509_set_issuer_name , .Fn X509_REQ_get_subject_name , and .Fn X509_REQ_set_subject_name first appeared in SSLeay 0.6.5.
