调试断言在FREAD失败（） [英] Debug assertion failed at fread()

问题描述

TEST.bin，烧写的大小为7,01,760字节。我想从这个文件作为一个缓冲区bufferPointer短阅读的日期。

The size of the test.bin is 7,01,760 bytes. I am trying to read date from this file as "short" in a buffer bufferPointer.

short * bufferPointer=NULL; 
// ==> ANSWER WAS ADDING: bufferPointer = ( short*)malloc(350880); <==
FILE *fp=fopen(" test.bin","rb");
fread(bufferPointer,sizeof(short),350880 ,fp); 
fclose(fp);

我正在调试断言失败在FREAD（）。为什么？

推荐答案

您应先用分配的内存到 bufferPointer 足够的量的malloc 。然后你可以使用 FREAD 从文件到该缓冲区中读取。

You should first allocate sufficient amount of memory to the bufferPointer by using malloc. Then you can use fread to read from the file into that buffer.
