Before the next COMMit, the size of the created buffer can be queried using SYSTem:
DATA:MEMory:SIZE?.
To delete the buffer and free its memory, use SYSTem:DATA:MEMory:DELete
<ShMemName>, or SYSTem:DATA:MEMory:RESet.
For background information, see Chapter 9.4.3, "Memory-mapped trace data transfer",
on page 246.
Setting parameters:
<ShMemName> Gives the shared memory buffer a name, which is required by
processes that want to access it.
The name must be unique within the running Windows instance.
The names of the shared memory buffers initialized using
SYSTem:DATA:MEMory:INITalize can be queried using
SYSTem:DATA:MEMory:CATalog?.
Usage: Setting only
SYSTem:DATA:MEMory:DELete <ShMemName>
Deletes a shared memory buffer <ShMemName> initialized using SYSTem:DATA:
MEMory:INITalize.
Before the SYSTem:DATA:MEMory:COMMit, an initialized shared memory buffer has
the temporary name NewMemory. Do not delete it.
Setting parameters:
<ShMemName> Unique name of the shared memory buffer.
Usage: Setting only
SYSTem:DATA:MEMory:INITalize
Initializes a new shared memory buffer.
●
Use SYSTem:DATA:MEMory:ADD to add traces to it.
●
Finally, use SYSTem:DATA:MEMory:COMMit to complete the setup and create the
named shared memory buffer in Windows.
For background information, see Chapter 9.4.3, "Memory-mapped trace data transfer",
on page 246.
Usage:
Event
SYSTem:DATA:MEMory:OFFSet?
Queries the offset in bytes of the last added trace data block, relative to the start of the
shared memory buffer (see SYSTem:DATA:MEMory:ADD).
The offset is required by processes that want to read the trace data from the buffer.
For background information, see Chapter 9.4.3, "Memory-mapped trace data transfer",
on page 246.
