Patch from Antonio SJ Musumeci: " This code with SDL-1.2.8 and CVS: #include <stdio.h> #include <stdlib.h> #include <SDL.h> int main(int argc, char** argv) { char alphabet[26] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; char buffer_file[27] = {0}; char buffer_mem[27] = {0}; int rv_file; int rv_mem; FILE* file_ptr; SDL_RWops* rwop_file; SDL_RWops* rwop_mem; file_ptr = fopen("./blah", "w"); fwrite(alphabet, 1, sizeof(alphabet), file_ptr); fclose(file_ptr); rwop_mem = SDL_RWFromMem(alphabet, sizeof(alphabet)); rwop_file = SDL_RWFromFile("./blah", "r"); rv_mem = SDL_RWread(rwop_mem , buffer_mem, 5, 6); rv_file = SDL_RWread(rwop_file, buffer_file, 5, 6); printf("From File: %d %s\n" "From Mem: %d %s\n", rv_file, buffer_file, rv_mem, buffer_mem); printf("Seek end of File: %d\n" "Seek end of Mem: %d\n", SDL_RWseek(rwop_file, 0, SEEK_END), SDL_RWseek(rwop_mem , 0, SEEK_END)); SDL_RWclose(rwop_file); SDL_RWclose(rwop_mem); return 0; } Produces this output: From File: 5 ABCDEFGHIJKLMNOPQRSTUVWXYZ From Mem: 5 ABCDEFGHIJKLMNOPQRSTUVWXY Seek end of File: 26 Seek end of Mem: 26 " --ryan.

To compile and install SDL:

    1.  Run './configure; make; make install'

        If you are compiling for Windows using gcc, read the FAQ at:
        http://www.libsdl.org/faq.php?action=listentries&category=4#42

        If you are compiling using Visual C++ on Win32, you should read
        the file VisualC.html

    2.  Look at the example programs in ./test, and check out the HTML
        documentation in ./docs to see how to use the SDL library.

    3.  Join the SDL developer mailing list by sending E-mail to
    	sdl-request@libsdl.org
        and put "subscribe" in the subject of the message.

        Or alternatively you can use the web interface:
            http://www.libsdl.org/mailing-list.php

That's it!
