## Member Function Documentation

virtual GtDeviceAddr gtpin::IGtProfileBuffer::DeviceAddr | ( | uint32_t | offset = `0` | ) | const`[pure virtual]`

Given offset within profile buffer, get virtual address of the corresponding device memory location.

Parameters:

  [in] | offset | Offset of the location within profile buffer

Returns:
  Address in the virtual address space of the device, or invalid address if offset > Size()

virtual bool gtpin::IGtProfileBuffer::Fill | ( | uint8_t | val = `0` | ) | `[pure virtual]`

Assign the given value to all bytes of this profile buffer.

Parameters:

  [in] | val | The value to be assigned

Returns:
  true - success, false - failure In case of error, the IGtCore::LastError() function provides the specific failure reason

virtual bool gtpin::IGtProfileBuffer::Fill | ( | uint32_t | offset,
|  | uint32_t | size,
|  | uint8_t | val
| ) |  | `[pure virtual]`

Assign the given value to all bytes of the specified memory block within profile buffer.

Parameters:

  [in] | offset | Offset of the memory block within profile buffer
  [in] | size | Number of bytes to fill in
  [in] | val | The value to be assigned

Returns:
  true - success, false - failure In case of error, the IGtCore::LastError() function provides the specific failure reason

virtual bool gtpin::IGtProfileBuffer::Read | ( | uint32_t | offset,
|  | void * | dst,
|  | uint32_t | size
| ) |  | const`[pure virtual]`

Copy memory block from the profile buffer into specified host memory location.

Parameters:

  [in] | offset | Offset of the memory block within profile buffer
  [in,out] | dst | Destination address in the host memory
  [in] | size | Number of bytes to copy

Returns:
  true - success, false - failure In case of error, the IGtCore::LastError() function provides the specific failure reason

virtual bool gtpin::IGtProfileBuffer::Write | ( | uint32_t | offset,
|  | const void * | src,
|  | uint32_t | size
| ) |  | `[pure virtual]`

Copy memory block from the specified host memory location into profile buffer.

Parameters:

  [in] | offset | Offset of the memory block within profile buffer
  [in] | src | Source address in the host memory
  [in] | size | Number of bytes to copy

Returns:
  true - success, false - failure In case of error, the IGtCore::LastError() function provides the specific failure reason
