I tried writing an app to access a file from the MS, but when I run the file, the PSP displays a black screen then turns off 10-20 seconds later.

Here is the code:

Code:
#include <pspdebug.h>
#include <pspiofilemgr.h>

PSP_MODULE_INFO("FileIOTest", 0, 1, 1);

int main()
{
   SceUID FileID;
   char *TestFile;

   pspDebugScreenInit();

   pspDebugScreenPrintData("File Access Test",16);

   FileID = sceIoOpen("ms0:/test.txt",PSP_O_RDONLY,0);

   pspDebugScreenSetXY(0,1);

   if (FileID == 0)
   {
      pspDebugScreenPrintData("Error Opening File",18);
   }
   else
   {
      pspDebugScreenPrintData("File Opened",11);

      sceIoRead(FileID,TestFile,10);

      pspDebugScreenSetXY(0,2);
      pspDebugScreenPrintData("File Accessed",13);

      pspDebugScreenSetXY(0,3);
      pspDebugScreenPrintData(TestFile,10);
   }

   while (1) {}

   return 0;
}


Where have I gone wrong?

Code:
char *TestFile;


This is a pointer to an array of char, but where is the actual array ?? In your example, it is not declared, so when you're writing into this array you're writing at a random place...

Replace it with this:
Code:
char TestFile[11]


That way, the compiler makes some room for the actual chars.

Thanks, I'm not too experienced with C.
