61B MemoryAllocation¶

Stub MON 61B (49 decimal) · Mnemonic FIXC5 · Group: Segment Administration (manual section 2.12)

Available from: not known - no compatibility box captured from the manual

Emulation source: src/handlers/mon_61B_MemoryAllocation.c

Description¶

Fixes or unfixes ND-100 segments to be used by the ND-500 Monitor. You may also reserve a contiguous area in physical memory. Various other memory functions are reserved for the ND-500 Monitor.

Notes¶

This monitor call is not normally used by ordinary programs.
You may use this monitor call to reserve space for DMA buffers.

Parameters¶

Name	Type	Direction	Description
`FuncCode`	INTEGER	In	Function code. Function codes 4, 5 and 6 are the only values allowed. The functions and parameters are described on the third page for this call.
`Param2`	INTEGER	I/O	Parameter 2. Depends on the function code.
`Param3`	INTEGER	I/O	Parameter 3. Depends on the function code.
`Param4`	INTEGER	I/O	Parameter 4. Depends on the function code.
`Param5`	INTEGER	I/O	Parameter 5. Depends on the function code.
`Param6`	INTEGER	I/O	Parameter 6. Depends on the function code.

Direction: In = the program supplies the value, Out = the call returns it, In/Out = both.

Compatibility¶

ND-100	ND-500	User programs	RT programs	System programs
Yes	No	Yes	Yes	Yes

From the YAML extraction; this call's page in the manual had no compatibility box that was captured.
