IntelliSense: argument of type "void *" is incompatible with parameter of type "FILE *" and Error C2664: 'fread' : cannot convert parameter 4 from 'void *' to 'FILE *' Any tips would be useful. I don't understand why we'd pass a void *stream to the function. What does that even mean? A pointer to a void? It is called here. /* we want to use our own read function */ curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_callback); CURL API CURLOPT_READFUNCTION Pass a pointer to a function that matches the following prototype: size_t function( void *ptr, size_t size, size_t nmemb, void *userdata); This function gets called by libcurl as soon as it needs to read data in order to send it to the peer. The data area pointed at by the pointer ptr may be filled with at most size multiplied with nmemb number of bytes. Your function must return the actual number of bytes that you stored in that memory area. Returning 0 will signal end-of-file to the library and cause it to stop the current transfer. If you stop the current transfer by returning 0 "pre-maturely" (i.e before the server expected it, like when you've said you will upload N bytes and you upload less than N bytes), 7 Years Ago Hello, I am doing simple read/write program for serial port.
