gnutls_x509_crl_get_extension_info — API function


#include <gnutls/x509.h>

int gnutls_x509_crl_get_extension_info(gnutls_x509_crl_t crl, unsigned indx, void * oid, size_t * sizeof_oid, unsigned int * critical);


gnutls_x509_crl_t crl
should contain a gnutls_x509_crl_t type
unsigned indx
Specifies which extension OID to send, use (0) to get the first one.
void * oid
a pointer to store the OID
size_t * sizeof_oid
initially holds the maximum size of oid , on return holds actual size of oid .
unsigned int * critical
output variable with critical flag, may be NULL.


This function will return the requested extension OID in the CRL, and the critical flag for it. The extension OID will be stored as a string in the provided buffer. Use gnutls_x509_crl_get_extension_data() to extract the data.

If the buffer provided is not long enough to hold the output, then * sizeof_oid is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.


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