NAME gnutls_x509_crq_get_attribute_info - API function
SYNOPSIS #include <gnutls/x509.h>
int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid);
ARGUMENTS gnutls_x509_crq_t crq should contain a gnutls_x509_crq_t structure
int indx Specifies which attribute OID to send. Use zero to get the first one.
void * oid a pointer to a structure to hold the OID
size_t * sizeof_oid initially holds the maximum size of oid, on return holds actual size of oid.
DESCRIPTION This function will return the requested attribute OID in the certifi- cate, 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.
RETURNS On success, GNUTLS_E_SUCCESS is returned, otherwise a negative value in case of an error. If your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
