SceDeci4pSDfMgrForKernel

sceSDfMgrOpenForKernel

Version NID
0.990-3.60 0xA55F5F0D

Acquires an interrupt-suspending lock and calls sceSDfMgrExOpenForKernel. 

SceSDfMgrSocketId sceSDfMgrOpenForKernel(SceSDfMgrEventHandler eventHandler, const SceSDfMgrOpenParam* openParam, void* pCommon);

sceSDfMgrExOpenForKernel

Version NID
0.990-3.60 0xCF4A3E03

Opens a SDfMgr socket. openParam is not retained and can be disposed of after this call. 

SceSDfMgrSocketId sceSDfMgrExOpenForKernel(SceSDfMgrEventHandler eventHandler, const SceSDfMgrOpenParam* openParam, void* pCommon);

sceSDfMgrExSendForKernel

Version NID
0.990-3.60 0xDAFE03AD

Sends up to bufLen bytes from buffer, and returns number of bytes sent on success.

Note that buffer is not const: this is not a typo. buffer may be written to under specific conditions. 

SceSSize sceSDfMgrExSendForKernel(SceSDfMgrSocketId sock, void* buffer, SceSize bufLen);

sceSDfMgrExReqSendForKernel

Version NID
0.990-3.60 0xB44083E1

Create data sending request on socket. This causes a SCE_DFMGR_EVENT_WRITE event to be received by the socket's event handler.

To send data on a Deci4p socket, first call sceSDfMgrExReqSendForKernel, then call sceSDfMgrExSendForKernel in the SCE_DFMGR_EVENT_WRITE event handler. 

int sceSDfMgrExReqSendForKernel(SceSDfMgrSocketId sock);

sceSDfMgrExRecvForKernel

Version NID
0.990-3.60 0xF43F5941

Receives up to bufLen bytes in buffer, and returns number of bytes received on success. 

SceSSize sceSDfMgrExRecvForKernel(SceSDfMgrSocketId sock, void* buffer, SceSize bufLen);

sceSDfMgrCloseForKernel

Version NID
0.990-3.60 0x86CFC8C6

Acquires an interrupt-suspending lock and calls sceSDfMgrExCloseForKernel. 

SceInt32 sceSDfMgrCloseForKernel(SceSDfMgrSocketId sock);

sceSDfMgrExCloseForKernel

Version NID
0.990-3.60 0x90E8D453

Close a SDfMgr socket. 

SceInt32 sceSDfMgrExCloseForKernel(SceSDfMgrSocketId sock);

sceSDfMgrBreakSystemForKernel

Version NID
0.990-3.60 0xEDFBA012

Sets up some internal state and calls SceKernelIntrMgr#sceKernelGenerateSoftIntrForDriver(0, 1, 0). 

SceInt32 sceSDfMgrBreakSystemForKernel(void);

sceSDfMgrContinueSystemForKernel

Version NID
0.990-3.60 0x9A653F19

SceInt32 sceSDfMgrContinueSystemForKernel(void);

SceDeci4pSDfMgrForKernel_A963E333

Version NID
0.990-3.60 0xA963E333

Calls sceSDfMgrExReqSend(sock), then may call an Host Interface function and/or call sceKernelGenerateSoftIntrForDriver(1, 0, targetLUT[sceKernelCpuId()]) where targetLUT = {1, 2, 4, 8}. 

SceInt32 SceDeci4pSDfMgrForKernel_A963E333(SceSDfMgrSocketId sock);

SceDeci4pSDfMgrForKernel_68903C1D

Version NID
0.990-3.60 0x68903C1D

Equivalent to SceDeci4pDfMgrForDebugger_CACAB5F9.

Reads value at ptr as a 3-byte unsigned integer and returns it. 

SceUInt32 SceDeci4pSDfMgrForKernel_68903C1D(void* ptr);

SceDeci4pSDfMgrForKernel_81E7C5BD

Version NID
0.990-3.60 0x81E7C5BD
