NAME gnutls_x509_crq_get_extension_by_oid - API function
SYNOPSIS #include <gnutls/x509.h>
int gnutls_x509_crq_get_extension_by_oid(gnutls_x509_crq_t crq, const char * oid, int indx, void * buf, size_t * sizeof_buf, unsigned int * critical);
ARGUMENTS gnutls_x509_crq_t crq should contain a gnutls_x509_crq_t structure
const char * oid holds an Object Identified in null terminated string
int indx In case multiple same OIDs exist in the extensions, this specifies which to send. Use zero to get the first one.
void * buf a pointer to a structure to hold the name (may be null)
size_t * sizeof_buf initially holds the size of buf
unsigned int * critical will be non zero if the extension is marked as critical
DESCRIPTION This function will return the extension specified by the OID in the certificate. The extensions will be returned as binary data DER encoded, in the provided buffer.
RETURNS On success, GNUTLS_E_SUCCESS is returned, otherwise a negative value in case of an error. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
