NAME

6       gnutls_x509_crq_get_extension_info - API function
7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int gnutls_x509_crq_get_extension_info(gnutls_x509_crq_t crq, int indx,
12       void * oid, size_t * sizeof_oid, unsigned int * critical);
13

ARGUMENTS

15       gnutls_x509_crq_t crq
16                   should contain a gnutls_x509_crq_t structure
17
18       int indx    Specifies which extension number to get. Use (0) to get the
19                   first one.
20
21       void * oid  a pointer to a structure to hold the OID
22
23       size_t * sizeof_oid
24                   initially  holds the maximum size of  oid , on return holds
25                   actual size of  oid .
26
27       unsigned int * critical
28                   output variable with critical flag, may be NULL.
29

DESCRIPTION

31       This function will return the requested extension OID in  the  certifi‐
32       cate,  and  the critical flag for it.  The extension OID will be stored
33       as a string in the  provided  buffer.   Use  gnutls_x509_crq_get_exten‐
34       sion_data() to extract the data.
35
36       If  the  buffer  provided is not long enough to hold the output, then *
37       sizeof_oid  is  updated  and   GNUTLS_E_SHORT_MEMORY_BUFFER   will   be
38       returned.
39

RETURNS

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