H****r 发帖数: 2801	1 How come this function declared differently by different compilers? It seems that VS2010 does not use this keyword?
t****t 发帖数: 6806	2 memcpy规定源和目的不能overlap, 和restricted目的一样. 所以有restricted就可以加上, 没有也没关系, 就靠程序员自觉了. 【在 H****r 的大作中提到】 : How come this function declared differently by different compilers? : It seems that VS2010 does not use this keyword?

H****r 发帖数: 2801	4 个人理解是可以加的啊，但是这个函数是在string.h里定义好的，而且有的document里说是已经改成restricted的了, 而有的还是没有这个关键字... 【在 t****t 的大作中提到】 : memcpy规定源和目的不能overlap, 和restricted目的一样. 所以有restricted就可以 : 加上, 没有也没关系, 就靠程序员自觉了.

t****t 发帖数: 6806	6 that doesn't matter to you, does it? you are not supposed to modify it anyway. just use it as you will normally do. 【在 H****r 的大作中提到】 : 个人理解是可以加的啊，但是这个函数是在string.h里定义好的，而且有的document里 : 说是已经改成restricted的了, 而有的还是没有这个关键字...
nr 发帖数: 67	7 y 【在 H****r 的大作中提到】 : memmove?
H****r 发帖数: 2801	8 主要是影响个人对这个关键字的理解，感觉说明档和实际实现不同了。后来查了下发现好像这个问题是Visual Studio貌似不用这个关键字，囧... 【在 t****t 的大作中提到】 : that doesn't matter to you, does it? you are not supposed to modify it : anyway. just use it as you will normally do.
