Here is the caller graph for this function:

put_bits_dbuff()

static int put_bits_dbuff ( fr_dbuff_t *  dbuff, uint8_t *  p, int  start_bit, uint8_t  num_bits, uint64_t  data  )

static

Put bits into an output dbuff.

Parameters

dbuff	where the bytes go
p	where leftover bits go
start_bit	start bit in the dbuff where the data goes, 0..7
num_bits	number of bits to write to the output, 0..55
data	data to write, all in the lower "num_bits" of the uint64_t variable

Returns

>= 0 the next value to pass in for start_bit < 0 no space or invalid start_bit or num_bits parameter
