# CTRunGetPositionsPtr(_:) Returns a direct pointer for the glyph position array stored in the run. ``` func CTRunGetPositionsPtr(_ run: CTRun) -> UnsafePointer? ``` ## Parameters `run` The run from which to access glyph positions. ## Return Value A valid pointer to an array of structures, or `NULL`. ## Discussion The glyph positions in a run are relative to the origin of the line containing the run. The position array will have a length equal to the value returned by [`CTRunGetGlyphCount(_:)`](/documentation/CoreText/CTRunGetGlyphCount(_:)). The caller should be prepared for this function to return `NULL` even if there are glyphs in the stream. If this function returns `NULL`, the caller must allocate its own buffer and call [`CTRunGetPositions(_:_:_:)`](/documentation/CoreText/CTRunGetPositions(_:_:_:)) to fetch the glyph positions. --- Copyright © 2026 Apple Inc.
