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

======================== Using SDL with PicoGUI ======================== - Originally contributed by Micah Dowty <micahjd@users.sourceforge.net> PicoGUI is a scalable GUI system with a unique architecture, primarily focused on scalability to various embedded systems. You can find more information including a FAQ at http://picogui.org To use the patch: 1. When compiling, add the "--enable-video-picogui" switch to ./configure 2. When running your program, ensure that the picogui driver for SDL is in use by setting the SDL_VIDEODRIVER environment variable to "picogui". 3. The program must also be linked to the C client library for PicoGUI (libpgui.so). If the program is being compiled with a patched SDL installed this should be done automatically. If you want to use an existing binary with PicoGUI, you can set the LD_PRELOAD environment variable to the path of your libpgui.so file. Capabilities: So far only basic functionality is provided on true color (linear16/24/32) devices. Accessing a memory mapped bitmap, updating the display, and handling mouse/keyboard input. This functionality has been tested with several applications, including mplayer, Xine, sldroids, and Abuse. TODO list: - YUV overlays will be helpful for watching video on set top boxes or other embedded devices that have some graphics acceleration hardware - Account for rotated bitmap storage in pgserver - Support for hiding or changing the cursor - The display should be centered when the SDL application is smaller than the PicoGUI panel - Fullscreen or any other special modes - Support for indexed and grayscale modes - Probably much more... --- The End ---
