NAME

gnutls_x509_crl_get_extension_info - Get extension id and criticality

SYNOPSIS

#include <gnutls/x509.h>

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

ARGUMENTS

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

DESCRIPTION

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.

RETURNS

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

SINCE

2.8.0
