Send binary file in HTTP response using C sockets

Question

I`m trying to send a binary file (png image) in http response.

FILE *file;
char *buffer;
int fileLen;

//Open file
file = fopen(\"1.png\", \"rb\");
if (!file         


        

Answer 1

strcat(reply, buffer); // this is incorrect, because png(buffer) may contain zero byte
send(client, reply, strlen(reply), 0);
strlen(reply) // this is incorrect, because png may contain zero byte
