Function Documentation

sceIoAddDrv()

int sceIoAddDrv

(

PspIoDrv *

drv

)

Adds a new IO driver to the system.

Note

This is only exported in the kernel version of IoFileMgr

Parameters

drv	- Pointer to a filled out driver structure

Returns

< 0 on error.

Example:

PspIoDrvFuncs host_funcs = { ... };
PspIoDrv host_driver = { "host", 0x10, 0x800, "HOST", &host_funcs };
sceIoDelDrv("host");
sceIoAddDrv(&host_driver);

sceIoChangeThreadCwd()

int sceIoChangeThreadCwd	(	SceUID	uid,
		char *	dir
	)

Set the current working directory for a thread.

Parameters

uid	- The UID of the thread
dir	- The directory to set

Returns

0 on success, < 0 on error

sceIoDelDrv()

int sceIoDelDrv

(

const char *

drv_name

)

Deletes a IO driver from the system.

Note

This is only exported in the kernel version of IoFileMgr

Parameters

drv_name

- Name of the driver to delete.

Returns

< 0 on error

Referenced by _gdbSupportLibInit().

sceIoGetThreadCwd()

int sceIoGetThreadCwd	(	SceUID	uid,
		char *	dir,
		int	len
	)

Get the current working directory for a thread.

Parameters

uid	- The UID of the thread
dir	- A character buffer in which to store the cwd
len	- The length of the buffer

Returns

Number of characters written to buf, if no cwd then 0 is returned.

sceIoReopen()

int sceIoReopen	(	const char *	file,
		int	flags,
		SceMode	mode,
		SceUID	fd
	)

Reopens an existing file descriptor.

Parameters

file	- The new file to open.
flags	- The open flags.
mode	- The open mode.
fd	- The old filedescriptor to reopen

Returns

< 0 on error, otherwise the reopened fd.
