gnutls_record_send_range: API function
NAMEgnutls_record_send_range - API function
- gnutls_session_t session
- is a gnutls_session_t structure.
- const void * data
- contains the data to send.
- size_t data_size
- is the length of the data.
- const gnutls_range_st * range
- is the range of lengths in which the real data length must be hidden.
DESCRIPTIONThis function operates like gnutls_record_send() but, while gnutls_record_send() adds minimal padding to each TLS record, this function uses the TLS extra-padding feature to conceal the real data size within the range of lengths provided. Some TLS sessions do not support extra padding (e.g. stream ciphers in standard TLS or SSL3 sessions). To know whether the current session supports extra padding, and hence length hiding, use the gnutls_record_can_use_length_hiding() function.
NOTEThis function currently is only limited to blocking sockets.
RETURNSThe number of bytes sent (that is data_size in a successful invocation), or a negative error code.
