函数名称:ldm_relative - Calculate the next relative offset*@buffer: Block of data being worked on*@buflen: Size of the block of data*@base: Size of the previous fixed width fields*@offset: Cumulative size of the previous variable-width fields* Because many of the

函数原型:static int ldm_relative(const u8 *buffer, int buflen, int base, int offset)

返回类型:int

624  base加等于offset
625  如果非bufferoffset小于0或base大于buflen
626  如果非bufferldm_error("!buffer")
628  如果offset小于0则ldm_error("offset (%d) < 0", offset)
630  如果base大于buflenldm_error("base (%d) > buflen (%d)", base, buflen)
632  返回:负1
634  如果basebuffer[base]大于等于buflen
635  ldm_error("base (%d) + buffer[base] (%d) >= buflen (%d)", base, buffer[base], buflen)
637  返回:负1
639  返回:buffer[base]加offset加1
