# [NAME](#NAME)

gnutls\_range\_split - API function

# [SYNOPSIS](#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](#ARGUMENTS)

[gnutls\_session\_t session](#gnutls_session_t)

is a **gnutls\_session\_t** type

[const gnutls\_range\_st * orig](#const)

is the original range provided by the user

[gnutls\_range\_st * next](#gnutls_range_st)

is the returned range that can be conveyed in a TLS record

[gnutls\_range\_st * remainder](#gnutls_range_st~2)

is the returned remaining range

# [DESCRIPTION](#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](#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 modified to store the resulting values.
