Name:seq_buf_hex_dump - print formatted hex dump into the sequence buffer*@s: seq_buf descriptor*@prefix_str: string to prefix each line with;* caller supplies trailing spaces for alignment if desired*@prefix_type: controls whether prefix of an offset,

Proto:int seq_buf_hex_dump(struct seq_buf *s, const char *prefix_str, int prefix_type, int rowsize, int groupsize, const void *buf, size_t len, bool ascii)

Type:int

Parameter:

365  If rowsize != 16 && rowsize != 32 Then rowsize = 16
368  When i < len cycle

370  remaining -= rowsize
372  hex_dump_to_buffer - convert a blob of data to "hex ASCII" in memory*@buf: data blob to dump*@len: number of bytes in the @buf*@rowsize: number of bytes to print per line; must be 16 or 32*@groupsize: number of bytes to print at a time (1, 2, 4, 8;
