Why am I getting an "Expected Identifier" error?

Error: expected primary-expression before 'read', PLEASE HELP?

• Answer:

  Check this line int bread = ssize_t read(filename,void *buf,size_t sizeof(buf)); Here ssize_t, are you typecasing? I think you have simply copied the prototype of the function read here. Send correct arguments filename string is not initialized. Also, read function first argument is file descriptor (integer) while you are sending a string See thefollowing line also. It is simply a prototype. You have to call it by sending arguments. int britten = ssize_t write(new_socket_fd,void *buf,size_t bread);
