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.
