gnutls_x509_crl_get_extension_info - Man Page

#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.
