gnutls_range_split(3) gnutls gnutls_range_split(3) NAME
gnutls_range_split - API function SYNOPSIS
#include <gnutls/gnutls.h> int gnutls_range_split(gnutls_session_t session, const gnutls_range_st * orig, gnutls_range_st * next, gnutls_range_st * remainder); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure const gnutls_range_st * orig is the original range provided by the user gnutls_range_st * next is the returned range that can be conveyed in a TLS record gnutls_range_st * remainder is the returned remaining range DESCRIPTION
This function should be used when it is required to hide the length of very long data that cannot be directly provided to gnutls_record_send_range(). In that case this function should be called with the desired length hiding range in orig . The returned next value should then be used in the next call to gnutls_record_send_range() with the partial data. That process should be repeated until remainder is (0,0). RETURNS
0 in case splitting succeeds, non zero in case of error. Note that orig is not changed, while the values of next and remainder are mod- ified to store the resulting values. REPORTING BUGS

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 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. 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 sessions). 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 only limited to blocking sockets. RETURNS
The number of bytes sent (that is data_size in a successful invocation), or a negative error code. REPORTING BUGS
