Data Buffer Classes
NVMeConsole has two data buffer classes.
One is DATAMEM, the other is PCMEM.
DATAMEM class
Properties
| Name | Description |
|---|---|
int size | The size assigned. If the size is zero, the data mem is not assigned. |
int datapattern | The data pattern of filled data. |
Methods
| Name | Description |
|---|---|
bool DataMem_Assign(int) | Assign data memory in byte size, |
string DataMem_Dump() | Print out whole data contents. |
string DataMem_HumanReadable(int startoffset, int size) | Print out human readable data contents |
void DataMem_SetDataPattern(int pattern) | Fill the memory with specific data pattern |
void DataMem_FromFile(string path) | Fill the memory from a file |
void DataMem_ToFile(string path) | Save the memory to file |
void DataMem_Write32(int offset, UInt32 data) | Write 4 bytes data to offset |
UInt32 DataMem_Read32(int offset) | Read 4 bytes from offset |
PCMEM class
Properties
| Name | Description |
|---|---|
int size | The size assigned. if the size is zero, the data mem is not assigned. |
bool forsystem | Physically contiguous memory. If true, the memory is not released when NVMeConsole is closed. |
address_l | Physical address lower of the assigned memory |
address_h | Physical address higher of the assigned memory |
Method
| Name | Description |
|---|---|
bool PCMem_Assign(int) | Assign physically contiguous memory in byte size. |
void PCMem_Free() | Release the memory |
string PCMem_Dump() | Print out whole memory contents |
void PCMem_FromFile(string path) | Fill the memory from a file |
void PCMem_ToFile(string path) | Save the memory to file |
void PCMem_Write32(int offset, UInt32 data) | Write 4 bytes data to offset |
UInt32 PCMem_Read32(int offset) | Read 4 bytes from offset |
