 Posted: Sat Feb 09, 2008 5:03 am Post subject: Get folder on MS |
 |
|
I am trying to find a way of getting the paths of each folder inside another folder, I couldn't find anything on the web.
I need that to see the homebrews so I can launch them from my app.
Thanks. |

Hi! :)
Have a look at pspiofilemgr.h and the functions sceIoDopen, sceIoDclose and sceIoDread.
Ciaooo

| Or just use standard opendir(), readdir(), closedir() functions, which take care of known problems with the sce functions. |

Hi Hedi
A short sample:

#include <pspkernel.h>
#include <pspdebug.h>
#include <pspctrl.h>
#include <pspiofilemgr_stat.h>
#include <string>
/* Define the module info section */

/* Define the main thread's attribute value (optional) */
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);
int sceInit(void);
int main( void)
{
int ret;
//System initilization
sceInit(); //set exit callback
pspDebugScreenInit(); //init the screen in a special mode that allow us to print on it easily
sceIoChdir( "ms0:/PSP/GAME/test"); //set the cuurent dir, so we can use relative path
sceIoMkdir( "toto",0777); //create a directory named "toto" in the current directory
//(we could have given the absolute path.
//777 is the standart permission for rwx for all
//Prints the name of all files and directories (including '.' and '..'
//1) open the directory
SceUID uid = sceIoDopen("ms0:/PSP/GAME/test");
struct SceIoDirent dirEnt;
dirEnt.d_private=NULL; //if not done the at the first use of dirEnt in sceIoDread => crash
//2) for all the enties => at least toto and the eboot.pbp
while(sceIoDread(uid, &dirEnt))
{
pspDebugScreenPrintf("Name: %s \n",dirEnt.d_name);
}
//we close the directory
sceIoDclose(uid);
//rename a directory
sceIoRename( "toto" , "titi" );
//delete a dir ( has to be empty!!)
sceIoRmdir( "titi");
pspDebugScreenPrintf("------------------------\n");

Try not to use hardcoded paths. Assuming your path is GAME can get you in trouble is the person puts it in GAME380, for example. Instead, get the path dynamically. Here's some common code for getting the path.
| Code: | // get launch directory name for our home
strncpy(psp_home,argv[0],sizeof(psp_home)-1);
psp_home[sizeof(psp_home)-1] = 0;
char *str_ptr=strrchr(psp_home,'/');
if (str_ptr){
str_ptr++;
*str_ptr = 0;
}
|
That code takes the first argument (which should be a full path and filename for the currently running app) and terminates the string after the rightmost '/' to give the path to the app. Note that it operates on a COPY of the argument. |

| And the SDK will do the path stuff for you, you don't need to call sceIoChdir at all as the initialization of the c library should have already done so :) |

unless you want to small down your application size and use the pspsdk libc instead of newlib :p |
