 Posted: Mon Aug 31, 2009 7:01 pm Post subject: using sceIoOpen and sceIoWrite |
 |
|
Hello all, right, i know how to check for a file using sceIoOpen simple stuff. But how do write using sceIoWite.
| Quote: | bytes_written = sceIoWrite(fd, data, 100);
|
How would i define, bytes_written. FD would be like sceUID FD right?
and also what about data. the 100 is the size of the file right? |

Is's basicly the same as in the normal libc (stdio.h - fopen/fwrite/fclose)
http://psp.jim.sh/pspsdk-doc/group__FileIO.html
And use better english?

sceIoOpen has not the standard form of fopen. But the other two have same parameters, you're right.

well i have this
SceUID test;
test = sceIoOpen("ms0:/test.txt", O_WRONLY|O_CREAT, 0777);
that will open test.txt for writing and will create the file if it dont exist.
now what do i do with sceIowrite?
im trying copy the contents ./test.txt to ms0:/test.txt |
