int gnutls_x509_crq_get_attribute_by_oid(gnutls_x509_crq_t crq, const char * oid, unsigned indx, void * buf, size_t * buf_size);
- gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
- const char * oid
holds an Object Identifier in null-terminated string
- unsigned indx
In case multiple same OIDs exist in the attribute list, this specifies which to get, use (0) to get the first one
- void * buf
a pointer to a structure to hold the attribute data (may be NULL)
- size_t * buf_size
initially holds the size of buf
This function will return the attribute in the certificate request specified by the given Object ID. The attribute will be DER encoded.
Attributes in a certificate request is an optional set of data appended to the request. Their interpretation depends on the CA policy.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
