NAME
gnutls_x509_crq_get_extension_info - API function
SYNOPSIS
#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);
ARGUMENTS
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.
DESCRIPTION
This function will return the requested extension OID in the certifi-
cate, and the critical flag for it. The extension OID will be stored
as a string in the provided buffer. Use gnutls_x509_crq_get_exten-
sion_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 re-
turned.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative er-
ror code in case of an error. If your have reached the last extension
available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
