 Posted: Mon May 16, 2005 8:18 am Post subject: problem with simple file copy code |
 |
|
bascially im trying to write a simple tool to copy TITLE.DB from my memory card to my pc but it seems to crash right after it accesses mc0:/BADATA-SYSTEM/TITLE.DB. im probably making some trivial mistake that hopefully someone more experienced can point out. here's my code:
| Code: | #include <tamtypes.h>
#include <kernel.h>
#include <sifrpc.h>
#include <loadfile.h>
#include <fileio.h>
#include <malloc.h>
#include <libmc.h>
#include <string.h>
#include <modload.h>
#define TYPE_XMC
void LoadModules(void);
int main() {
SifInitRpc(0);
LoadModules();
int inF, ouF;
char line[512];
int bytes;
if((inF = fioOpen("mc0:/BADATA-SYSTEM/TITLE.DB", O_RDONLY)) < 0) {
scr_printf("error opening <mc0:/BADATA-SYSTEM/TITLE.DB>!");
exit(-1);
}
if((ouF = fioOpen("host:TITLE.DB", O_WRONLY | O_CREAT)) < 0) {
scr_printf("error writing <host:TITLE.DB>!");
exit(-1);
}
while((bytes = fioRead(inF, line, sizeof(line))) > 0)
fioWrite(ouF, line, bytes);
fioClose(inF);
fioClose(ouF);
SifExitRpc();
SleepThread();
return 0;
}
void LoadModules(void)
{
int ret;
#ifdef TYPE_MC
ret = SifLoadModule("rom0:SIO2MAN", 0, NULL);
if (ret < 0) {
printf("Failed to load module: SIO2MAN");
SleepThread();
}
ret = SifLoadModule("rom0:MCMAN", 0, NULL);
if (ret < 0) {
printf("Failed to load module: MCMAN");
SleepThread();
}
ret = SifLoadModule("rom0:MCSERV", 0, NULL);
if (ret < 0) {
printf("Failed to load module: MCSERV");
SleepThread();
}
#else
ret = SifLoadModule("rom0:XSIO2MAN", 0, NULL);
if (ret < 0) {
printf("Failed to load module: SIO2MAN");
SleepThread();
}
ret = SifLoadModule("rom0:XMCMAN", 0, NULL);
if (ret < 0) {
printf("Failed to load module: MCMAN");
SleepThread();
}
ret = SifLoadModule("rom0:XMCSERV", 0, NULL);
if (ret < 0) {
printf("Failed to load module: MCSERV");
SleepThread();
}
#endif
}

It just seems to hang after accessing mc0:/ and no file is created on host:/ even though fioOpen returns 0.
I have no idea as to why. |

If all you want is a copy of the file, do you really need to write a whole elf just to do that?
Try | Code: | | ps2client copyfrom mc0:/BADATA-SYSTEM/TITLE.DB host:TITLE.DB |
Thats how i get stuff off/on a mc. I'm not at my dev machine right now, but im pretty sure thats right.
PS: you may need a slightly older version of ps2client..i've heard rumours the netfs functions were pulled out recently?? i dunno.
PPS: you have to load ps2netfs.irx from ps2sdk first...
EDIT: Now recent ckeckouts of ps2client also come with a program fsclient that takes this functionality off ps2client
