Function Documentation

void* sceKernelAllocHeapMemory (  SceUID  heapid, SceSize  size )

Allocate a memory block from a heap. Parameters: heapid  - The UID of the heap to allocate from. size  - The number of bytes to allocate. Returns: The address of the allocated memory block, or NULL on error.

SceUID sceKernelCreateHeap (  SceUID  partitionid, SceSize  size, int  unk, const char *  name )

Create a heap. Parameters: partitionid  - The UID of the partition where allocate the heap. size  - The size in bytes of the heap. unk  - Unknown, probably some flag or type, pass 1. name  - Name assigned to the new heap. Returns: The UID of the new heap, or if less than 0 an error.

int sceKernelDeleteHeap (  SceUID  heapid  )

Delete a heap. Parameters: heapid  - The UID of the heap to delete. Returns: 0 on success, < 0 on error.

int sceKernelFreeHeapMemory (  SceUID  heapid, void *  block )

Free a memory block allocated from a heap. Parameters: heapid  - The UID of the heap where block belongs. block  - The block of memory to free from the heap. Returns: 0 on success, < 0 on error.

SceSize sceKernelHeapTotalFreeSize (  SceUID  heapid  )

Get the amount of free size of a heap, in bytes. Parameters: heapid  - The UID of the heap Returns: the free size of the heap, in bytes. < 0 on error.

SceSize sceKernelPartitionMaxFreeMemSize (  int  pid  )

Get the size of the largest free memory block. Parameters: pid  - The partition id Returns: The size of the largest free memory block, in bytes.

SceSize sceKernelPartitionTotalFreeMemSize (  int  pid  )

Get the total amount of free memory. Parameters: pid  - The partition id Returns: The total amount of free memory, in bytes.

int sceKernelQueryMemoryPartitionInfo (  int  pid, PspSysmemPartitionInfo *  info )

Query the parition information. Parameters: pid  - The partition id info  - Pointer to the PspSysmemPartitionInfo structure Returns: 0 on success.

int sceKernelSetDdrMemoryProtection (  void *  addr, int  size, int  prot )

Set the protection of a block of ddr memory. Parameters: addr  - Address to set protection on size  - Size of block prot  - Protection bitmask Returns: < 0 on error

void sceKernelSysMemDump (  void   )

Get the kernel to dump the internal memory table to Kprintf.

void sceKernelSysMemDumpBlock (  void   )

Dump the list of memory blocks.

void sceKernelSysMemDumpTail (  void   )

Dump the tail blocks.
