函数名称:map_onto - translate one bitmap relative to another*@dst: resulting translated bitmap*@orig: original untranslated bitmap*@relmap: bitmap relative to which translated*@bits: number of bits in each of these bitmaps* Set the n-th bit of @dst iff there

函数原型:void bitmap_onto(unsigned long *dst, const unsigned long *orig, const unsigned long *relmap, unsigned int bits)

返回类型:void

参数:
