relay_file_read_end

函数名称：lay_file_read_end_pos - return the new read position*@read_pos: file read position*@buf: relay channel buffer*@count: number of bytes to be read

函数原型：static size_t relay_file_read_end_pos(struct rchan_buf *buf, size_t read_pos, size_t count)

返回类型：size_t

参数：

类型	参数	名称
struct rchan_buf *	buf
size_t	read_pos
size_t	count

1102

subbuf_size等于 sub-buffer size

1103

n_subbufs等于 number of sub-buffers per buffer

1105

read_subbuf等于read_pos除subbuf_size

1106

padding等于padding counts per sub-buffer [read_subbuf]

1107

如果read_pos取模subbuf_size加count加padding恒等于subbuf_size则end_pos等于read_subbuf加1的和乘subbuf_size

1109

否则end_pos等于read_pos加count

1111

如果end_pos大于等于subbuf_size乘n_subbufs则end_pos等于0

1114

返回:end_pos
