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
