10
11       int  gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, unsigned
12       indx, void * oid, size_t * sizeof_oid);
13

ARGUMENTS

15       gnutls_x509_crq_t crq
16                   should contain a gnutls_x509_crq_t type
17
18       unsigned indx
19                   Specifies which attribute number to get. Use (0) to get the
20                   first one.
21
22       void * oid  a pointer to a structure to hold the OID
23
24       size_t * sizeof_oid
25                   initially  holds the maximum size of  oid , on return holds
26                   actual size of  oid .

DESCRIPTION

29       This function will return the requested attribute OID in  the  certifi‐
30       cate,  and  the critical flag for it.  The attribute OID will be stored
31       as a string in the  provided  buffer.   Use  gnutls_x509_crq_get_attri‐
32       bute_data() to extract the data.
33
34       If  the  buffer  provided is not long enough to hold the output, then *
35       sizeof_oid is updated  and  GNUTLS_E_SHORT_MEMORY_BUFFER  will  be  re‐
36       turned.
37

RETURNS

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