Api function
Usage
#include <gnutls/x509.h>
int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, unsigned indx, void * oid, size_t * sizeof_oid);
Arguments
gnutls_x509_crq_t crq
|
should contain a |
|---|---|
unsigned indx
|
Specifies which attribute number to get. Use (0) 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 . |
Overview
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.
Returns
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.
