NAME¶gnutls_x509_crq_get_key_purpose_oid - API function
int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t crq, unsigned indx, void * oid, size_t * sizeof_oid, unsigned int * critical);
- gnutls_x509_crq_t crq
- should contain a gnutls_x509_crq_t type
- unsigned indx
- This specifies which OID to return, use (0) to get the first one
- void * oid
- a pointer to store the OID (may be NULL)
- size_t * sizeof_oid
- initially holds the size of oid
- unsigned int * critical
- output variable with critical flag, may be NULL.
