seq_buf_putmem_hex

Name:seq_buf_putmem_hex - write raw memory into the buffer in ASCII hex*@s: seq_buf descriptor*@mem: The raw memory to write its hex ASCII representation of*@len: The length of the raw memory to copy (in bytes)* This is similar to seq_buf_putmem() except

Proto:int seq_buf_putmem_hex(struct seq_buf *s, const void *mem, unsigned int len)

Type:int

Parameter:

Type	Parameter	Name
struct seq_buf *	s
const void *	mem
unsigned int	len

225

data = mem

229

WARN_ON(size == 0)

231

When len cycle

232

start_len = min - return minimum of two values of the same or compatible types*@x: first value*@y: second value(len, HEX_CHARS - 1)

236

When i >= 0 cycle

238

hex[j++] = hex_asc_hi(data[i])

239

hex[j++] = hex_asc_lo(data[i])

241

If WARN_ON_ONCE(j == 0 || j / 2 > len) Then Break

245

len -= j / 2

246

hex[j++] = ' '

seq_buf_putmem - write raw data into the sequenc buffer*@s: seq_buf descriptor*@mem: The raw memory to copy into the buffer*@len: The length of the raw memory to copy (in bytes)* There may be cases where raw memory needs to be written into the

249

If seq_buf have a buffer that might overflow. When this happens* the len and size are set to be equal. Then Return -1

252

Return 0
