Detailed Description

Power-off library.

Poweroff is a library that substitutes for the missing poweroff functionality in rom0:CDVDMAN, which is offered by newer CDVDMAN modules (i.e. sceCdPoweroff). Other than allowing the PlayStation 2 to be switched off via software means, this is used to safeguard against the user switching off/resetting the console before data can be completely written to disk.

Typedef Documentation

poweroff_callback

typedef void(*) poweroff_callback(void *arg)

User defined function for use in poweroffSetCallback().

In fact there can be anything. This function will be called when power button is pressed. In common cases it should end everything and poweroff console. You should close all files (close(fd)) and unmount all partitions. If you use PFS, close all files and unmount all partitions.

fileXioDevctl("pfs:", PDIOC_CLOSEALL, NULL, 0, NULL, 0)

Shut down DEV9 (Network module), if you used it:

while(fileXioDevctl("dev9x:", DDIOC_OFF, NULL, 0, NULL, 0) < 0){};

Last function inside callback should be poweroffShutdown().

Function Documentation

poweroffChangeThreadPriority()

void poweroffChangeThreadPriority ( int priority )

extern

Change thread priority.

The callback thread runs at priority POWEROFF_THREAD_PRIORITY by default. You can change the priority by calling this function after poweroffSetCallback(). You can call this function before poweroffSetCallback() as well (but after poweroffInit() ). In that case poweroffSetCallback() will be registered with the provided priority.

Definition at line 119 of file poweroff.c.

poweroffInit()

int poweroffInit ( void )

extern

Initializes the poweroff library.

A service thread with a default priority of POWEROFF_THREAD_PRIORITY will be created.

Definition at line 64 of file poweroff.c.

poweroffSetCallback()

void poweroffSetCallback ( poweroff_callback cb, void * arg )

extern

Set callback function.

Parameters

[in]	cb	Function that will be called when power button is pressed.
[in]	arg	Arguments that are sent to cb function (can be NULL)

Callback function should be user-defined elsewhere. There are some standart specifications.
