Function Documentation

◆ VITASDK_BUILD_ASSERT_EQ() [1/2]

VITASDK_BUILD_ASSERT_EQ	(	0x40	,
		SceExcpmgrData
	)

◆ VITASDK_BUILD_ASSERT_EQ() [2/2]

◆ ksceExcpmgrGetData()

SceExcpmgrData* ksceExcpmgrGetData ( void )

Get a pointer to SceExcpmgr's internal data.

This is only used by exception handlers.

Returns: pointer to SceExcpmgrData structure

◆ ksceExcpmgrRegisterHandler()

int ksceExcpmgrRegisterHandler	(	SceExcpKind	kind,
		int	priority,
		void *	handler
	)

Register an exception handler.

handler must point to eight bytes of space followed by the handler code. The space will be used in the internal linked list structure.

Parameters

[in]	kind	The kind of exception
[in]	priority	The priority (must be 0 <= priority < 8), 0 highest
	handler	The handler

Returns: Error code or zero on success
