Function Documentation

int QueryIntrHandlerInfo	(	SceUID	intr_code,
		SceUID	sub_intr_code,
		PspIntrHandlerOptionParam *	data
	)

void sceKernelCpuResumeIntr

(

unsigned int

flags

)

Resume all interrupts.

Parameters:

flags

- The value returned from sceKernelCpuSuspendIntr().

void sceKernelCpuResumeIntrWithSync

(

unsigned int

flags

)

Resume all interrupts (using sync instructions).

Parameters:

flags

- The value returned from sceKernelCpuSuspendIntr()

unsigned int sceKernelCpuSuspendIntr

(

void

)

Suspend all interrupts.

Returns:

The current state of the interrupt controller, to be used with sceKernelCpuResumeIntr().

int sceKernelDisableSubIntr	(	int	intno,
		int	no
	)

Disable a sub interrupt handler.

Parameters:

	intno	- The sub interrupt to disable.
	no	- The sub interrupt handler number

Returns:

< 0 on error.

int sceKernelEnableSubIntr	(	int	intno,
		int	no
	)

Enable a sub interrupt.

Parameters:

	intno	- The sub interrupt to enable.
	no	- The sub interrupt handler number

Returns:

< 0 on error.

int sceKernelIsCpuIntrEnable

(

void

)

Determine if interrupts are enabled or disabled.

Returns:

1 if interrupts are currently enabled.

int sceKernelIsCpuIntrSuspended

(

unsigned int

flags

)

Determine if interrupts are suspended or active, based on the given flags.

Parameters:

flags

- The value returned from sceKernelCpuSuspendIntr().

Returns:

1 if flags indicate that interrupts were not suspended, 0 otherwise.

int sceKernelRegisterSubIntrHandler	(	int	intno,
		int	no,
		void *	handler,
		void *	arg
	)

Register a sub interrupt handler.

Parameters:

	intno	- The interrupt number to register.
	no	- The sub interrupt handler number (user controlled)
	handler	- The interrupt handler
	arg	- An argument passed to the interrupt handler

Returns:

< 0 on error.

int sceKernelReleaseSubIntrHandler	(	int	intno,
		int	no
	)

Release a sub interrupt handler.

Parameters:

	intno	- The interrupt number to register.
	no	- The sub interrupt handler number

Returns:

< 0 on error.
