gnutls_x509_crq_get_extension_data - API function
#include <gnutls/x509.h>
int gnutls_x509_crq_get_extension_data(gnutls_x509_crq_t crq,
unsigned indx, void * data, size_t * sizeof_data);
gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
unsigned indx
Specifies which extension number to get. Use (0) to get
the first one.
void * data a pointer to a structure to hold the data (may be null)
size_t * sizeof_data
initially holds the size of oid
This function will return the requested extension data in the
certificate. The extension data will be stored as a string in the
provided buffer.
Use gnutls_x509_crq_get_extension_info() to extract the OID and
critical flag. Use gnutls_x509_crq_get_extension_by_oid() instead,
if you want to get data indexed by the extension OID rather than
sequence.
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.
