C:发送文件到套接字

问题描述

我正在尝试使用套接字发送二进制文件.

I`m trying to send binary file using socket.

        FILE *file;
        char *file_data;
        file = fopen(filepath, "rb");

        //Allocate memory
        file_data=(char *)malloc(fileLen+1);

        //Read file contents into buffer
        fread(file_data, fileLen, 1, file);
        fclose(file);

        sent = send(client, file_data, strlen(header)+fileLen, 0);

它可以正常工作，但是某些文件太大，我想读取要缓冲的部分，发送，然后读取第二部分，发送，依此类推.

It works OK, but some files a too large and I want to read a part to buffer, send it, then read the second part, send it and so on.

我尝试使用fread和fgets来获得零件，但是我失败了=(如何正确执行?

I tried to get parts using fread and fgets, but i failed =( How to do it correctly?

UPD:问题在于读取客户端的传入请求.我没看过.如果我这样做，那没什么不好的事

UPD: the trouble was in reading incoming request from client. I didnt read it. If i do it, nothing bad happens
