167B AttachSegment¶

Stub MON 167B (119 decimal) · Mnemonic REENT · Group: Segment Administration (manual section 2.12)

Available from: All programs (manual compatibility box)

Emulation source: src/handlers/mon_167B_AttachSegment.c

Description¶

Attaches a reentrant segment to your two current segments. The address areas of the segments may overlap. Pages in the reentrant segment may be accessed for reading, writing, or fetching instructions. When written to, a page loses its reentrancy. It is stored on one of your current overlapping segments.

Notes¶

The segment is treated as reentrant only for the RT programs which have attached it.
Parts of the reentrant segment may not be outside the address area of your current segments. OUTSIDE SEGMENT BOUNDS is output if these parts are written to.

Parameters¶

Name	Type	Direction	Description
`SegmentNumber`	INTEGER	In	Segment number of the reentrant segment. See @LIST-REENTRANT.

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

The manual's compatibility box for this call, word for word.

Yes/no fields from the YAML extraction (not in the manual's words):

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

Disagreement

The manual box says ND-100, but the yes/no fields say ND-100 = Yes, ND-500 = Yes. The manual box is the source.
