gnutls_record_send_range(3) gnutls gnutls_record_send_range(3) NAME gnutls_record_send_range - API function SYNOPSIS #include <gnutls/gnutls.h> ssize_t gnutls_record_send_range(gnutls_session_t session, const void * data, size_t data_size, const gnutls_range_st * range); ARGUMENTS gnutls_session_t session is a gnutls_session_t type. 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. DESCRIPTION This 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 ses- sions). To know whether the current session supports extra padding, and hence length hiding, use the gnutls_record_can_use_length_hiding() function. NOTE This function currently is limited to blocking sockets. RETURNS The number of bytes sent (that is data_size in a successful invoca- tion), or a negative error code.
