bool c_tcp_ts_lsb_code ( const struct rohc_comp_ctxt *const  context,
const uint32_t  timestamp,
const size_t  nr_bits_minus_1,
const size_t  nr_bits_0x40000,
const size_t  nr_bits_0x4000000,

)

Compress the TimeStamp option value.

See RFC4996 page 65

Parameters
contextThe compression context
timestampThe timestamp value to compress
nr_bits_minus_1The minimal number of required bits for p = -1
nr_bits_0x40000The minimal number of required bits for p = 0x40000
nr_bits_0x4000000The minimal number of required bits for p = 0x4000000
[out]rohc_dataThe ROHC packet being built
rohc_max_lenThe max remaining length in the ROHC buffer
[out]rohc_lenThe length appended in the ROHC buffer
Returns
true if compression was successful, false otherwise
