返回一个值。 [英] Returning a value.

问题描述

我将结构的指针值从一个函数返回到main;但每当它进入main时它变为NULL ...我在main中使用了另一个指针并将其值等同于返回指针但它仍然变为NULL。我也尝试从main中删除它的初始化;但是ivvain。

那么，保留其价值的是什么呢？其实我想在其他功能中使用相同的值; m从main调用。

I m returning a value of pointer of a structure from one function to main; but whenever it comes in main it becomes NULL... i used another pointer in main and equated its value to returning pointer but its still becoming NULL. I also tried removing its initialization from main; but ivvain.
So, what is to be donr to retain its value? Actually i want to use the same value in other function; which m calling from main.
