函数名称：add_short_data_template

函数原型：static int add_short_data_template(struct sw842_param *p, u8 b)

返回类型：int

参数：

类型参数名称
struct sw842_param *p
u8b
331  如果非b或b大于SHORT_DATA_BITS_MAX则返回:负EINVAL
334  ret等于add_bits(p, sw only template - this is not in the hw design; it's used only by this* software compressor and decompressor, to allow input buffers that aren't* a multiple of 8., additional bits of each op param )
335  如果ret则返回:ret
338  ret等于add_bits(p, b, SHORT_DATA_BITS)
339  如果ret则返回:ret
342  以i小于b循环
343  ret等于add_bits(p, in[i], 8)
344  如果ret则返回:ret
348  如果sw842_template_counts则atomic_inc( & template_short_data_count)
351  返回:0
