我想在内存中把这个变量的数据替换，可是没成功，原来是图片比如想替换成文本的字节集，怎么改变原来的变量缓冲大小谢谢

wtflxk

给你换了一张图片，图片有点大调试输出有点慢

怎么改变变量a1的长度不再是原来大小，有没有替换原数据变新数据大小

m718195

我想做的让变量变成我后面写进去的字节集大小，

三咲阳光

申请指定长度的内存

m718195

实在案例中我只有这个变量的指针，我应该题目改：怎么通过指针来改变原变量数据的大小.有一种情况可能我新写进去大小比原来数据大的话也许可以覆盖，关键是我写进去的数据比原来小，调试输出还是显示指针所在变量数据大小还是之前的大小

申请指定长度的内存

我只有原变量指针地址，难道还可以重新给一个有数据的变量重新申请内存大小吗

m718195

一个屁

申请指定长度的内存
