gnutls_x509_crq_get_attribute_info - API function

#include <gnutls/x509.h>

int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, unsigned indx, void * oid, size_t * sizeof_oid);

should contain a gnutls_x509_crq_t type
Specifies which attribute number to get. Use (0) to get the first one.
a pointer to a structure to hold the OID
initially holds the maximum size of oid , on return holds actual size of oid .

This function will return the requested attribute OID in the certificate, and the critical flag for it. The attribute OID will be stored as a string in the provided buffer. Use gnutls_x509_crq_get_attribute_data() to extract the data.

If the buffer provided is not long enough to hold the output, then * sizeof_oid is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error. If your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
