gnutls_x509_...y_purpose_oid(3) gnutls gnutls_x509_...y_purpose_oid(3)
gnutls_x509_crt_get_key_purpose_oid - API function
#include <gnutls/x509.h>
int gnutls_x509_crt_get_key_purpose_oid(gnutls_x509_crt_t cert,
unsigned indx, void * oid, size_t * oid_size, unsigned int *
critical);
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
unsigned indx
This specifies which OID to return. Use (0) to get
the first one.
void * oid a pointer to a buffer to hold the OID (may be null)
size_t * oid_size
initially holds the size of oid
unsigned int * critical
output flag to indicate criticality of extension
This function will extract the key purpose OIDs of the
Certificate specified by the given index. These are stored in
the Extended Key Usage extension (2.5.29.37) See the GNUTLS_KP_*
definitions for human readable names.
If oid is null then only the size will be filled. The oid
returned will be null terminated, although oid_size will not
account for the trailing null.
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long
enough, and in that case the *oid_size will be updated with the
required size. On success 0 is returned.
