NAME

6       gnutls_x509_crq_get_key_purpose_oid - API function
7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t crq, unsigned
12       indx, 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 type
17
18       unsigned indx
19                   This specifies which OID to return,  use  (0)  to  get  the
20                   first one
21
22       void * oid  a pointer to store the OID (may be NULL)
23
24       size_t * sizeof_oid
25                   initially holds the size of  oid
26
27       unsigned int * critical
28                   output variable with critical flag, may be NULL.
