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.
