<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>X509_NAME_ENTRY_get_object() retrieves the field name of <b>ne</b> in and <b>ASN1_OBJECT</b> structure.</p>

<p>X509_NAME_ENTRY_get_data() retrieves the field value of <b>ne</b> in and <b>ASN1_STRING</b> structure.</p>

<p>X509_NAME_ENTRY_set_object() sets the field name of <b>ne</b> to <b>obj</b>.</p>

<p>X509_NAME_ENTRY_set_data() sets the field value of <b>ne</b> to string type <b>type</b> and value determined by <b>bytes</b> and <b>len</b>.</p>

<p>X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_create_by_OBJ() create and return an <b>X509_NAME_ENTRY</b> structure.</p>

<h1 id="NOTES">NOTES</h1>

<p>X509_NAME_ENTRY_get_object() and X509_NAME_ENTRY_get_data() can be used to examine an <b>X509_NAME_ENTRY</b> function as returned by X509_NAME_get_entry() for example.</p>

<p>X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_OBJ(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_set_data() are seldom used in practice because <b>X509_NAME_ENTRY</b> structures are almost always part of <b>X509_NAME</b> structures and the corresponding <b>X509_NAME</b> functions are typically used to create and add new entries in a single operation.</p>

<p>The arguments of these functions support similar options to the similarly named ones of the corresponding <b>X509_NAME</b> functions such as X509_NAME_add_entry_by_txt(). So for example <b>type</b> can be set to <b>MBSTRING_ASC</b> but in the case of X509_set_data() the field name must be set first so the relevant field information can be looked up internally.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>X509_NAME_ENTRY_get_object() returns a valid <b>ASN1_OBJECT</b> structure if it is set or NULL if an error occurred.</p>

<p>X509_NAME_ENTRY_get_data() returns a valid <b>ASN1_STRING</b> structure if it is set or NULL if an error occurred.</p>

<p>X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on success or 0 on error.</p>

<p>X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_create_by_OBJ() return a valid <b>X509_NAME_ENTRY</b> on success or NULL if an error occurred.</p>
