gnutls_x509_c...xtension_info(3) gnutls gnutls_x509_c...xtension_info(3)
gnutls_x509_crq_get_extension_info - API function
#include <gnutls/x509.h>
int gnutls_x509_crq_get_extension_info(gnutls_x509_crq_t crq,
unsigned indx, void * oid, size_t * sizeof_oid, unsigned int *
critical);
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 * 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
certificate, and the critical flag for it. The extension OID
will be stored as a string in the provided buffer. Use
gnutls_x509_crq_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.
